This patch adds option "-m|--mod" to lsinitrd to list dracut

773d6a7ded lsinitrd.sh: don't choke on LZO-compressed images
lsinitrd (and hence dracut) currently fail to list the contents of any

83c9ff7dbb bonding: use hwaddr of the slave rather than the master
When a bonded interface is brought up, any slaves included in the bond
have their hardware address set to that of the bond master.  Although
this allows an interface to be brought up on start up, when the
configuration file is imported into the booted system it prevents
the bonded interface being successfully restarted.

The fix involves obtaining the hardware address of the slaves before
they are added to the bond and then using this value in the
configuration file.

827ec27a9c kernel-modules: Fix storage module selection for sdhci/mmc/ahci
Currently the block driver detection for generic initrd doesn't include
the SD/MMC drivers so we fail to boot generic images on any device using
those platforms as boot devices when using a generic initrd. Add logic
to detect those modules. This primarily fixes embedded ARM devices but
also likely intel tablets/dev boards and enterprise hypervisors that
have the ability to boot from SD.

Also the ahci_init_controller misses a number of drivers that use the
libahci_platform module for the init so this fixes some missing achi
moduless too.

Finally it cleans up the ARM storage module hacks that the above now
deals with in a more generic manner.

It turns out that commit f30b74e (dracut-initqueue service runs before
remote-fs-pre.target) is partial fix for remote fs mounts. Because no
one pulls in remote-fs.target, we can never start remote fs mounts.

If the luks device is specified by-id in /etc/crypttab and rd.luks.uuid not

crypto services which depend on those missing devices until it times out and
exits to dracut rescue shell.

2c19a5fa78 Specify strstr tightly, add strglob/strglobin.
By convention, strstr should be a literal string match. Previously, it
would match as a glob pattern. Some code used that, so add new
functions strglob and strglobin to do what that code expects, and
specify them tightly too. strglob tests whether the glob pattern
matches the entire string (the name strglob is also used in the yorick
language, and that's what it does there), while strglobin tests whether
the glob pattern matches anywhere in the string.

Also tightens str_starts, str_ends, and str_replace to deal with
literal strings only. In a quick grep I did not find code that depended
on these functions matching globs.

Changes the call sites where strstr was used with glob patterns to use
strglobin or strglob as the intention seemed to be (or, in one case,
strstr with the * removed as it did not affect the result anyway).

    fstab: do not mount and fsck from fstab if using systemd

But systemd doesn't mount nfs at all, because no unit is pulling in
remote-fs.target.

dracut must pull in these remote fs mount and all these remote mounts
should start only after network is up (ie. after dracut-initqueue).

e920bfb1e8 fstab: do not mount and fsck from fstab if using systemd
If using systemd in initramfs, we could run into a race condition when
dracut and systemd both are trying to mount and run fsck for the same
filesystem, and mount or fsck could be a failure.

To fix such failure, we should use systemd to mount/fsck from /etc/fstab
only.

5f6a495bf4 add default values in fstab_lines
It's useful for passing a full fstab line including like fs_passno so fsck
can take effect.

Previously it's assumed that there's no fs_freq and fs_passno in fstab lines
so original code just append "0 0" at the end of each fstab lines.

Improve this issue by assign default value in case they are not passed in.
Three field are handled here:
fs_mntops: default to "defaults"
fs_freq: default to "0"
fs_passno: default to "2"

8da51857f0 dracut.sh: Fix variable name typo.
This caused the root_dev variable not to be set which in turn meant that
the root device was not whitelisted in 99base/module-setup.sh when injecting
compile-time devexists hooks in hostonly initrds. This ties the generated
initrd to the root fs device (typically the UUID) rather than relying solely
only the root= kernel command line.

While it is hostonly, not hardcoding e.g. UUIDs is still desirable. Any
swap partition on the host device is still added however.

missing for the specific dracut module.

This unifies the way of checking for binaries and makes the life of an
initramfs creator easier, if he wants to find out why a specific dracut
module is not included in the initramfs.

659dc319d9 Dracut: Add a new argument "--rebuild"
Add "rebuild" option to dracut to  append the current  arguments
to those with  which the input initramfs image was  built.  This
option helps in incrementally building initramfs for testing.

    Usage: dracut [output_file] --rebuild input_file

If optional output file  is not provided, input file provided to
rebuild will be used as output file.

This patch alters  the creation of the initramfs image by adding
the file "/tmp/params.txt" to the image. Command line parameters
excluding "--rebuild",  input  &  output image names and "kernel
version" are stored in this file.  In case "--rebuild" parameter
is specified, "/tmp/params.txt" file, if present in input image,
is read and its contents "prepend"ed to the current command line
parameters, that is if such a file is already present. Also,  it
stores the  cumulative parameters to the file "/tmp/params.txt",
in the  new image. This patch  has been tested successfully on a
PowerBox with f19. It does not alter the behaviour of any of the
existing  options.

e3469d76c7 crypt: Prevent asking for password multiple times if non-default crypt name is used.
If a non-default device mapper name is used for an encrypted partion is
used, (i.e. not luks-$UUID) due to parsing of /etc/crypttab, then the
short-circuits put in place to prevent asking the password twice do not
work.

This would not normally be an issue as the settled job itself should be
removed after it has run and thus cannot be run again. Sadly, due to
the corresponding udev rule using ACTION="add|changed", and the fact
that trying to unlock the device (whether successful or not) seems to
trigger a changed event, it means the settled job is recreated with
each itteration thus causing the whole loop to run again.

It is this situation that the short-circuit exits would normally come
into play but sadly do not work when non-standard names are used.

By the time the /tmp/cryptroot-asked-$2 file is written near the end of
the script, the value of $2 has already been lost due to the argument
parsing code's use of 'shift'. So while on systems where the default
name is used are protected by checking /dev/mapper/xxxx, the
/tmp/cryptroot-asked-$2 file didn't help on systems where this was not
used due to this bug.

So this commit shuffles things around somewhat such that:

 1. The /dev/mapper/xxxx device is checked *after* resolving $2 (which
    contains the default name) to whatever /etc/crypttab specifies.
 2. The cryptroot-asked-xxxx file also uses the translated name both
    for the initial check and to flag when it's written.

As a separate fix, it might make sense to change the udev rule to only
act on add events rather than add|change events, but I'm not sure of the
ramifications of such a change and there may be cases where the add
event is missed and thus the change event needs to be included.

1d50dfe602 dracut-functions.sh: Avoid loading unnecessary 32-bit libraries for 64-bit initrds
Due to the 'inst_libdir_file "libnss_files*"' in the udev-rules module
this caues the /usr/lib/libnss_files-2.18.so* to be included. This is a
32-bit library and pulls in a 32-bit version of glibc also even on a
64-bit system.

This is due to the fact that ldconfig -pN will print [/usr]/lib paths
from the cache as well as [/usr]/lib64. As we handle these paths
specifically we should ignore these results from the cache.

Also there was a missing space when appending the ldconfig paths
onto our list meaning the last builtin and first ldconfig path
were unusable.

871c8e40d1 Add lzo, lz4 compression and read INITRD_COMPRESS
This patch adds support for lzop(1) & lz4(1) compression
algorithms to compress iniramfs image file. Both are supported
by the Linux kernel.

Linux kernel exports user's choice of initramfs compression
algorithm as a shell environment variable: INITRD_COMPRESS.
This patch adds support to read this variable and duly compress
the initramfs image file.

Environment variable INITRD_COMPRESS has less precedence than the
command line options --gzip, etc. Ie. command line options could
override the compression algorithm defined by $INITRD_COMPRESS.

3622d6d7b0 dmsquash-live: add /dev/mapper/live-base
This is similar to the reason for adding the
/run/initramfs/live-baseloop symlink -- access to the original live
image without overlays.

livemedia-creator does not create a osmin.img, so there is no mountable
device for it to use when rsyncing the live image to the target. It
needs a device that points to the original live image without overlays.

Note that lmc won't be creating osmin.img, since really isn't needed any
longer. Its purpose was to provide a minimal image that could be dd'd to
the target. Now that we use rsync this is no longer necessary.

The included patch adds a /dev/mapper/live-base device that Anaconda can
use whether or not there is an osmin present.

b874d4b5be lvm/mdraid: Fix LVM on MD activation
The 69-dm-lvm-metad.rules set some udev env. variables that makes it
possible to detect the right time to activate LVM on MD. The MD is very
similar to DM during activation - it's usable only after proper device
activation - the CHANGE event. We need to make a difference between a
CHANGE event that comes from this activation and CHANGE event that is
the outcome of the WATCH udev rule (otherwise we'd end up with LVM
activation done on each CHANGE event - which is wrong).

So we need the udev databse to be persistent during pivot to root fs
even for MD devices.

63f3bcd852 ifup: do not dhcp on network interface of secondary stack
Configure cmdline to:
 ip=br0:dhcp bridge=br0:bond0 bond=bond0:eth0

By default ifup bond0 will run dhcp on bond0, which is wrong. bond0
isn't the top interface. we should really run dhcp on br0.

So if we ifup an network interface on secondary stack, we should not
dhcp. Fix this issue with this patch.

36b2e5e2c2 dracut.sh: Fixup previous commit to only read /sys and /proc in hostonly mode
The gnome-ostree build system generates dracut initramfs images on the
build server, therefore not in hostonly mode.  The build system at the
moment doesn't mount /sys, and the previous commit caused a hard
failure due to lack of /sys/devices.

Because we only want /sys/devices in hostonly mode, just move those
bits inside the hostonly conditional above.

b2fab575dc dracut-lib: do not use cached CMDLINE in _getcmdline
Cached CMDLINE doesn't work 100%. For example the following case,

1. dracut starts to run dracut-cmdline.sh. CMDLINE is cached when calling
   getarg 'rd.break=cmdline'.
2. In 92-parse-ibft.sh, ibft_to_cmdline() calls $(set_ifname ibft xx:xx..)
   multiple times in each subshell.
3. In 1st call, set_ifname() will check $(getargs ifname) and write out
   ifname=xxxx accordingly.
4. In 2nd call, set_ifname() will check $(getargs ifname) and it's wrong here.
   Because in step 3, we introduce a new cmdline arg ifname=xxx, but CMDLINE
   isn't updated. Thus we fail to get the new ifname arg.

It's doable to unset CMDLINE every time after a new cmdline arg is in. But
unset should be done in the parent process, because unset CMDLINE in a
subshell won't unset CMDLINE in its parent or sibling process. And also it's
painful to unset CMDLINE every time. In the future, functions and code
snippet could probably separate or move to other file, the unset CMDLINE could
malfunction again like this time.

So I'm thinking not to cache CMDLINE. It's doesn't hurt to re-read all the
cmdline args everytime. Because it's in initramfs, a non cached _getcmdline()
should be fast enough.

Please consider!

Thanks

de74e1ef41 Rewrite "rootok" and "netroot" logic
Previously if "$rootok" = 1, parsing of netroot command line arguments
was skipped. For multiple netroot arguments, all parse scripts have to
run.

Previously only the first netroot argument was taken into account for
the parsing scripts. Now every netroot argument is processed.

f2cbd4cbd6 net-lib: ibft_to_cmdline() fixes
Fix 3 issues in ibft_to_cmdline():
- unset local variables at the beginning of each loop
- only write vlan.conf when we write out ip=xxx
- when vlan id is 0, don't write out vlan.conf. Because 0 means untagged
  and we don't actually need vlan interface.

==========
- "rd.cmdline=ask" will ask the user on the console to enter additional
kernel command line parameters
- "rd.hostonly=0" removes all "hostonly" added custom files,
which is useful in combination with "rd.auto" or other specific parameters,
if you want to boot on the same hardware, but the compiled in configuration
does not match your setup anymore
- inst* functions and dracut-install now accept the "-H" flag, which logs all
installed files to /lib/dracut/hostonly-files. This is used to remove those
files, if rd.hostonly is given on the kernel command line
- strstr now only does literal string match,
please use strglob and strglobin for globs
- fixed unpacking of the microcode image on shutdown
- added systemd-gpt-auto-generator
- fcoe: wait for lldpad to be ready
- network: handle "ip=dhcp6"
- network: DCHPv6: set valid_lft and preferred_lft
- dm: support dm-cache
- fstab: do not mount and fsck from fstab if using systemd
- break at switch_root only for bare rd.break and not for any rd.break=...
- nbd: make use of "--systemd-mark", otherwise it gets killed on switch_root
- fcoe-uefi: fixed cmdline parameter generation
- iscsi: deprecate "ip=ibft", use "rd.iscsi.ibft[=1]" from now on
- "lsinitrd -m" now only lists the dracut modules of the image
- a lot of small bugfixes

Toggle hostonly cmdline storing in the initramfs
--hostonly-cmdline:
Store kernel command line arguments needed in the initramfs
--no-hostonly-cmdline:

- dracut: --mount now understands full fstab lines
- dracut now also includes drivers from the /lib/modules/<version>/updates directory
- dracut: only set the owner of files to 0:0, if generated as non-root
- dracut now directly writes to the initramfs file
- dracut: call lz4 with the legacy flag (linux kernel does not support the new format)
- systemd: rootfs-generator generates JobTimeout=0 units for the root device
- systemd: added the systemd-sysctl service
- systemd: add 80-net-setup-link.rules and .link files for persistent interface renaming
- systemd: make dracut-shutdown.service failure non-fatal
- network: various IPv6 fixes
- network: DCHCP for IPv6
- network: understand ip=.....:<dns1>:<dns2>
- network: parse ibft nameserver settings
- shutdown: if kexec fails, just reboot
- lvm: handle one LV at a time with lvchange
- module-setup.sh:
New functions require_binaries() and require_any_binary() to be used
in the check() section of module-setup.sh.
- a lot of small bugfixes

dracut-036
==========
- fixed skipcpio signature checking
dracut-035
==========
- changed dracut tarball compression to xz
- new argument "--rebuild"
- add lzo, lz4 compression
- install: install all binaries with <name> found in PATH
- lsinitrd can now handle initramfs images with an early cpio prepended
(microcode, ACPI tables)
- mkinitrd-suse added as a compat stub for dracut
- lvm: install thin utils for non-hostonly
- resume: fix swap detection in hostonly
- avoid loading unnecessary 32-bit libraries for 64-bit initrds
- crypt: wait for systemd password agents
- crypt: skip crypt swaps with password files
- network: before doing dhcp, dracut now checks, if the link has a carrier
- network: dhclient-script.sh now sets the lease time
- network: include usbnet drivers
- network: include all ethernet drivers
- network: add rd.bootif=0 to ignore BOOTIF
- i18n: introduce i18n_install_all, to install everything i18n related
- support SuSE DASD configurations
- support SuSE zfcp configurations
- support SuSE compressed KEYMAP= setting
- usrmount: always install the module,
so always mount /usr from within the initramfs
- test/TEST-17-LVM-THIN: new test case for lvm thin pools
- "halt" the machine in systemd mode for die()
dracut-034
==========
- do not run dhcp on parts of assembled network interfaces (bond, bridge)
- add option to turn on/off prelinking
--prelink, --noprelink
do_prelink=[yes|no]
- add ACPI table overriding
- do not log to syslog/kmsg/journal for UID != 0
- lvm/mdraid: Fix LVM on MD activation
- bcache module removed (now in bcache-tools upstream)
- mdadm: also install configs from /etc/mdadm.conf.d
- fixes for mdadm-3.2.6+
- mkinitrd: better compat support for SUSE
- fcoe: add FCoE UEFI boot device support
- rootfs-block: add support for the rootfallback= kernel cmdline option

dracut-033
==========
- improved hostonly device recognition
- improved hostonly module recognition
- add dracut.css for dracut.html
- do not install udev rules from /etc in generic mode
- fixed LABEL= parsing for swap devices
- fixed iBFT network setup
- url-lib.sh: handle 0-size files with curl
- dracut.asc: document debugging dracut on shutdown
- if rd.md=0, use dmraid for imsm and ddf
- skip empty dracut modules
- removed caching of kernel cmdline
- fixed iso-scan, if the loop device driver is a kernel module
- bcache: support new blkid
- fixed ifup udev rules
- ifup with dhcp, if no "ip=" specified for the interface

EXAMPLE
-------
To create a initramfs image, the most simple command is:
----
# dracut
----
This will generate a general purpose initramfs image, with all possible
functionality resulting of the combination of the installed dracut modules and
system tools. The image is /boot/initramfs-_++<kernel version>++_.img and
contains the kernel modules of the currently active kernel with version
_++<kernel version>++_.
If the initramfs image already exists, dracut will display an error message, and
to overwrite the existing image, you have to use the --force option.
----
# dracut --force
----
If you want to specify another filename for the resulting image you would issue
a command like:
----
# dracut foobar.img
----
To generate an image for a specific kernel version, the command would be:
----
# dracut foobar.img 2.6.40-1.rc5.f20
----
A shortcut to generate the image at the default location for a specific kernel
version is:
----
# dracut --kver 2.6.40-1.rc5.f20
----
If you want to create lighter, smaller initramfs images, you may want to specify
the --hostonly or -H option. Using this option, the resulting image will
contain only those dracut modules, kernel modules and filesystems, which are
needed to boot this specific machine. This has the drawback, that you can't put
the disk on another controller or machine, and that you can't switch to another
root filesystem, without recreating the initramfs image. The usage of the
--hostonly option is only for experts and you will have to keep the broken
pieces. At least keep a copy of a general purpose image (and corresponding
kernel) as a fallback to rescue your system.

functionality resulting of the combination of the installed dracut modules and
system tools. The image is /boot/initramfs-_++<kernel version>++_.img and

_++<kernel version>++_.

to overwrite the existing image, you have to use the --force option.
----
# dracut --force
----
If you want to specify another filename for the resulting image you would issue
a command like:
----
# dracut foobar.img
----
To generate an image for a specific kernel version, the command would be:
----
# dracut foobar.img 2.6.40-1.rc5.f20
----
A shortcut to generate the image at the default location for a specific kernel
version is:
----
# dracut --kver 2.6.40-1.rc5.f20
----
If you want to create lighter, smaller initramfs images, you may want to specify
the --host-only or -H option. Using this option, the resulting image will
contain only those dracut modules, kernel modules and filesystems, which are
needed to boot this specific machine. This has the drawback, that you can't put
the disk on another controller or machine, and that you can't switch to another
root filesystem, without recreating the initramfs image. The usage of the
--host-only option is only for experts and you will have to keep the broken
pieces. At least keep a copy of a general purpose image (and corresponding
kernel) as a fallback to rescue your system.
=== Inspecting the Contents
To see the contents of the image created by dracut, you can use the lsinitrd tool.
----
# lsinitrd /boot/initramfs-$(uname -r).img | less
----
To display the contents of a file in the initramfs also use the lsinitrd tool:
----
# lsinitrd /boot/initramfs-$(uname -r).img /etc/ld.so.conf
include ld.so.conf.d/*.conf
----
=== Adding dracut Modules
Some dracut modules are turned off by default and have to be activated manually.
You can do this by adding the dracut modules to the configuration file
_/etc/dracut.conf_ or _/etc/dracut.conf.d/myconf.conf_. See <<dracutconf5>>.
You can also add dracut modules on the command line
by using the -a or --add option:
----
# dracut --add bootchart initramfs-bootchart.img
----
To see a list of available dracut modules, use the --list-modules option:
----
# dracut --list-modules
----
or, if you have a dracut version earlier than +008+, issue the command:
----
# for mod in /usr/lib/dracut/modules.d/*; do echo ${mod##*/??}; done
----
=== Omitting dracut Modules
Sometimes you don't want a dracut module to be included for reasons of speed,
size or functionality. To do this, either specify the omit_dracutmodules
variable in the _dracut.conf_ or _/etc/dracut.conf.d/myconf.conf_ configuration
file (see <<dracutconf5>>), or use the -o or --omit option
on the command line:
----
# dracut -o "multipath lvm" no-multipath-lvm.img
----
=== Adding Kernel Modules
If you need a special kernel module in the initramfs, which is not
automatically picked up by dracut, you have the use the --add-drivers option
on the command line or the drivers vaiable in the _/etc/dracut.conf_
or _/etc/dracut.conf.d/myconf.conf_ configuration file (see <<dracutconf5>>):
----
# dracut --add-drivers mymod initramfs-with-mymod.img
----
== Boot parameters
The generated initramfs.img file normally does not contain any system
configuration files (except for some special exceptions), so the configuration
has to be done on the kernel command line. With this flexibility, you can easily
boot from a changed root partition, without the need to recompile the initramfs
image. So, you could completly change your root partition (move it inside a md
raid with encryption and LVM on top), as long as you specify the correct
filesystem LABEL or UUID on the kernel command line for your root device, dracut
will find it and boot from it.
The kernel command line usually can be configured in _/boot/grub/grub.conf_, if
grub is your bootloader and it also can be edited in the real boot process in
the grub menu.
The kernel command line can also be provided by the dhcp server with the
root-path option. See <<NetworkBoot>>.
For a full reference of all kernel command line parameters, see <<dracut8>>.
=== Specifying the root Device
This is the only option dracut really needs to boot from your root partition.
Because your root partition can live in various environments, there are a lot of
formats for the root= option. The most basic one is root=_++<path to device
node>++_:
----
root=/dev/sda2
----
Because device node names can change, dependent on the drive ordering, you are
encouraged to use the filesystem identifier (UUID) or filesystem label (LABEL)
to specify your root partition:
----
root=UUID=19e9dda3-5a38-484d-a9b0-fa6b067d0331
----
or
----
root=LABEL=myrootpartitionlabel
----
To see all UUIDs or LABELs on your system, do:
----
# ls -l /dev/disk/by-uuid
----
or
----
# ls -l /dev/disk/by-label
----
If your root partition is on the network see <<NetworkBoot>>.
=== Keyboard Settings
If you have to input passwords for encrypted disk volumes, you might want to set
the keyboard layout and specify a display font.
A typical german kernel command would contain:
----
vconsole.font=latarcyrheb-sun16 vconsole.keymap=de-latin1-nodeadkeys locale.LANG=de_DE.UTF-8
----
Setting these options can override the setting stored on your system, if you use
a modern init system, like systemd.
For dracut versions prior to version +008+ the line would look like:
----
LANG=de_DE.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=de-latin1-nodeadkeys
----
=== Blacklisting Kernel Modules
Sometimes it is required to prevent the automatic kernel module loading of a
specific kernel module. To do this, just add rd.blacklist=_++<kernel module
name>++_, with _++<kernel module name>++_ not containing the _.ko_
suffix, to the kernel command line. For example:
----
rd.driver.blacklist=mptsas rd.driver.blacklist=nouveau
----
The option can be specified multiple times on the kernel command line.
=== Speeding up the Boot Process
If you want to speed up the boot process, you can specify as much information
for dracut on the kernel command as possible. For example, you can tell dracut,
that you root partition is not on a LVM volume or not on a raid partition, or
that it lives inside a specific crypto LUKS encrypted volume. By default, dracut
searches everywhere. A typical dracut kernel command line for a plain primary or
logical partition would contain:
----
rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0
----
On systems with dracut version prior to +008+ the line would look like:
----
rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM
----
This turns off every automatic assembly of LVM, MD raids, DM raids and crypto LUKS.
Of course, you could also omit the dracut modules in the initramfs creation
process, but then you would lose the posibility to turn it on on demand.
[[Injecting]]
=== Injecting custom Files
To add your own files to the initramfs image, you have several possibilities.
The --include option let you specify a source path and a target path. For example
----
# dracut --include cmdline-preset /etc/cmdline.d/mycmdline.conf initramfs-cmdline-pre.img
----
will create an initramfs image, where the file cmdline-preset will be copied
inside the initramfs to _/etc/cmdline.d/mycmdline.conf_. --include can only be specified once.
----
# mkdir rd.live.overlay
# mkdir rd.live.overlay/etc
# mkdir rd.live.overlay/etc/conf.d
# mkdir rd.live.overlay/etc/cmdline.d
# echo "ip=auto" >> rd.live.overlay/etc/cmdline.d/mycmdline.conf
# echo export FOO=testtest >> rd.live.overlay/etc/conf.d/testvar.conf
# echo export BAR=testtest >> rd.live.overlay/etc/conf.d/testvar.conf
# tree rd.live.overlay/
rd.live.overlay/
└── etc
├── cmdline.d
│   └── mycmdline.conf
└── conf.d
└── testvar.conf
# dracut --include rd.live.overlay / initramfs-rd.live.overlay.img
----
This will put the contents of the rd.live.overlay directory into the root of the
initramfs image.
The --install option let you specify several files, which will get installed in
the initramfs image at the same location, as they are present on initramfs
creation time.
----
# dracut --install 'strace fsck.ext3 ssh' initramfs-dbg.img
----
This will create an initramfs with the strace, fsck.ext3 and ssh executables,
together with the libraries needed to start those. The --install option can be
specified multiple times.
[[NetworkBoot]]
== Network Boot
If your root partition is on a network drive, you have to have the network
dracut modules installed to create a network aware initramfs image.
On a Red Hat Enterprise Linux or Fedora system, this means, you have to install
the _dracut-network_ rpm package:
----
# yum install dracut-network
----
The resulting initramfs image can be served by a boot manager residing on your
local hard drive or it can be served by a PXE/TFTP server.
How to setup your PXE/TFTP server can be found in the
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/[Red
Hat Enterprise Linux Storage Administration Guide].
If you specify ip=auto on the kernel command line, then dracut asks a dhcp
server about the ip adress for the machine. The dhcp server can also serve an
additional root-path, which will set the root device for dracut. With this
mechanism, you have static configuration on your client machine and a
centralized boot configuration on your TFTP/DHCP server. If you can't pass a
kernel command line, then you can inject _/etc/cmdline.d/mycmdline.conf_, with a method described
in <<Injecting>>.
=== Reducing the Image Size
To reduce the size of the initramfs, you should create it with by ommitting all
dracut modules, which you know, you don't need to boot the machine.
You can also specify the exact dracut and kernel modules to produce a very tiny
initramfs image.
For example for a NFS image, you would do:
----
# dracut -m "nfs network base" initramfs-nfs-only.img
----
Then you would boot from this image with your target machine and reduce the size
once more by creating it on the target machine with the --host-only option:
----
# dracut -m "nfs network base" --host-only initramfs-nfs-host-only.img
----
This will reduce the size of the initramfs image significantly.

== Troubleshooting
If the boot process does not succeed, you have several options to debug the
situation. Some of the basic operations are covered here. For more information
you should also visit:
http://fedoraproject.org/wiki/How_to_debug_Dracut_problems
[[identifying-your-problem-area]]
=== Identifying your problem area
. Remove ''rhgb'' and ''quiet'' from the kernel command line
. Add ''rd.shell'' to the kernel command line. This will present a shell should
dracut be unable to locate your root device
. Add ''rd.shell rd.debug log_buf_len=1M'' to the kernel command line so that
dracut shell commands are printed as they are executed
. With dracut >= 002-11, you can inspect the rd.debug output with:
+
----
# less /run/initramfs/init.log
# dmesg | less
----
. With dracut >= 022 and systemd, you can inspect the rd.debug output with:
----
# journalctl -ab
----
. With dracut >= 025 the file /run/initramfs/rdsosreport.txt is generated, which contains all the logs and the output of all significant tools, which are mentioned later.
If you want to save that output, simply mount /boot by hand or insert an USB stick and mount that.
Then you can store the output for later inspection.

==== Using the dracut shell
dracut offers a shell for interactive debugging in the event dracut fails to
locate your root filesystem. To enable the shell:
. Add the boot parameter ''rd.shell'' to your bootloader configuration file
(e.g. _/etc/grub.conf_)
. Remove the boot arguments ''rhgb'' and ''quiet''

[[accessing-the-root-volume-from-the-dracut-shell]]
==== Accessing the root volume from the dracut shell
From the dracut debug shell, you can manually perform the task of locating and
preparing your root volume for boot. The required steps will depend on how your
root volume is configured. Common scenarios include:
* A block device (e.g. _/dev/sda7_)
* A LVM logical volume (e.g. _/dev/VolGroup00/LogVol00_)
* An encrypted device (e.g. _/dev/mapper/luks-4d5972ea-901c-4584-bd75-1da802417d83_)
* A network attached device (e.g. netroot=iscsi:@192.168.0.4::3260::iqn.2009-02.org.fedoraproject:for.all)
The exact method for locating and preparing will vary. However, to continue with
a successful boot, the objective is to locate your root volume and create a
symlink _/dev/root_ which points to the file system. For example, the following
example demonstrates accessing and booting a root volume that is an encrypted
LVM Logical volume.

= Developer Manual
== dracut Components
dracut uses a modular system to build and extend the initramfs image. All
modules are located in _/usr/lib/dracut/modules.d_ or in _<git-src>/modules.d_.
The most basic dracut module is _99base_. In _99base_ the initial shell script
init is defined, which gets run by the kernel after initramfs loading. Although
you can replace init with your own version of _99base_, this is not encouraged.
Instead you should use, if possible, the hooks of dracut. All hooks, and the
point of time in which they are executed, are described in <<stages>>.
The main script, which creates the initramfs is dracut itsself. It parses all
arguments and sets up the directory, in which everything is installed. It then
executes all check, install, installkernel scripts found in the modules, which
are to be processed. After everything is installed, the install directory is
archived and compressed to the final initramfs image. All helper functions used
by check, install and installkernel are found in in the file _dracut-functions_.
These shell functions are available to all module installer (install,
installkernel) scripts, without the need to source _dracut-functions_.
A module can check the preconditions for install and installkernel with the
check script. Also dependencies can be expressed with check. If a module passed
check, install and installkernel will be called to install all of the necessary
files for the module. To split between kernel and non-kernel parts of the
installation, all kernel module related parts have to be in installkernel. All
other files found in a module directory are module specific and mostly are hook
scripts and udev rules.
[[stages]]
== Boot Process Stages
dracut modules can insert custom script at various points, to control the boot
process.
These hooks are plain directories containing shell scripts ending with ".sh",
which are sourced by init.
Common used functions are in _dracut-lib.sh_, which can be sourced by any script.
=== Hook: cmdline
The _cmdline_ hook is a place to insert scripts to parse the kernel command line
and prepare the later actions, like setting up udev rules and configuration
files.
In this hook the most important environment variable is defined: root. The
second one is rootok, which indicates, that a module claimed to be able to parse
the root defined. So for example, **root=**__iscsi:....__ will be claimed by the
iscsi dracut module, which then sets rootok.
=== Hook: pre-udev
This hook is executed right after the cmdline hook and a check if root and
rootok were set. Here modules can take action with the final root, and before
udev has been run.
=== Start Udev
Now udev is started and the logging for udev is setup.
=== Hook: pre-trigger
In this hook, you can set udev environment variables with **udevadm control
--property=KEY=_value_** or control the further execution of udev with
udevadm.
=== Trigger Udev
udev is triggered by calling udevadm trigger, which sends add events for all
devices and subsystems.
=== Main Loop
In the main loop of dracut loops until udev has settled and
all scripts in _initqueue/finished_ returned true.
In this loop there are three hooks, where scripts can be inserted
by calling /sbin/initqueue.
==== Initqueue
This hook gets executed every time a script is inserted here, regardless of the
udev state.
==== Initqueue settled
This hooks (initqueue/settled) gets executed every time udev has settled.
==== Initqueue timeout
This hooks (initqueue/timeout) gets executed, when the main loop counter becomes half of the
rd.retry counter.
==== Initqueue finished
This hook (initqueue/finished) is called after udev has settled and
if all scripts herein return 0 the main loop will be ended.
Abritary scripts can be added here, to loop in the
initqueue until something happens, which a dracut module wants to wait for.
=== Hook: pre-mount
Before the root device is mounted all scripts in the hook pre-mount are
executed. In some cases (e.g. NFS) the real root device is already mounted,
though.
=== Hook: mount
This hook is mainly to mount the real root device.
=== Hook: pre-pivot
This hook is called before cleanup hook, This is a good place for
actions other than cleanups which need to be called before pivot.
=== Hook: cleanup
This hook is the last hook and is called before init finally switches root to
the real root device. This is a good place to clean up and kill processes not
needed anymore.
=== Cleanup and switch_root
Init (or systemd) kills all udev processes, cleans up the environment,
sets up the arguments for the real init process and finally calls switch_root.
switch_root removes the whole filesystem hierarchy of the initramfs,
chroot()s to the real root device and calls /sbin/init with the specified arguments.
To ensure all files in the initramfs hierarchy can be removed, all processes
still running from the initramfs should not have any open file descriptors left.
== Network Infrastructure
FIXME
== Writing a Module
A simple example module is _96insmodpost_, which modprobes a kernel module after
udev has settled and the basic device drivers have been loaded.
All module installation information is in the file module-setup.sh.
First we create a check() function, which just exits with 0 indicating that this
module should be included by default.
check():
----
return 0
----
The we create the install() function, which installs a cmdline hook with
priority number 20 called _parse-insmodpost.sh_. It also installs the
_insmodpost.sh_ script in _/sbin_.
install():
----
inst_hook cmdline 20 "$moddir/parse-insmodpost.sh"
inst_simple "$moddir/insmodpost.sh" /sbin/insmodpost.sh
----
The _pase-instmodpost.sh_ parses the kernel command line for a argument
rd.driver.post, blacklists the module from being autoloaded and installs the
hook _insmodpost.sh_ in the _initqueue/settled_.
_parse-insmodpost.sh_:
----
for p in $(getargs rd.driver.post=); do
echo "blacklist $p" >> /etc/modprobe.d/initramfsblacklist.conf
_do_insmodpost=1
done
[ -n "$_do_insmodpost" ] && /sbin/initqueue --settled --unique --onetime /sbin/insmodpost.sh
unset _do_insmodpost
----
_insmodpost.sh_, which is called in the _initqueue/settled_ hook will just
modprobe the kernel modules specified in all rd.driver.post kernel command line
parameters. It runs after udev has settled and is only called once (--onetime).
_insmodpost.sh_:
----
. /lib/dracut-lib.sh
for p in $(getargs rd.driver.post=); do
modprobe $p
done
----
=== check()
_check()_ is called by dracut to evaluate the inclusion of a dracut module in
the initramfs.
$hostonly:: If the $hostonly variable is set, then the module check() function
should be in "hostonly" mode, which means, that the check() should only return
0, if the module is really needed to boot this specific host.
check() should return with:
0:: Include the dracut module in the initramfs.
1:: Do not include the dracut module. The requirements are not fullfilled
(missing tools, etc.)
255:: Only include the dracut module, if another module requires it or if
explicitly specified in the config file or on the argument list.
=== depends()
The function depends() should echo all other dracut module names the module
depends on.

[IMPORTANT]
=====================
It is recommended to either bind an interface to a MAC with the **ifname**
argument, or to use the systemd-udevd predictable network interface names.
Predictable network interface device names based on:
- firmware/bios-provided index numbers for on-board devices
- firmware-provided pci-express hotplug slot index number
- physical/geographical location of the hardware
- the interface's MAC address
See:
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames
Two character prefixes based on the type of interface:
en:: ethernet
wl:: wlan
ww:: wwan
Type of names:
o<index>:: on-board device index number
s<slot>[f<function>][d<dev_id>]:: hotplug slot index number
x<MAC>:: MAC address
[P<domain>]p<bus>s<slot>[f<function>][d<dev_id>]:: PCI geographical location
[P<domain>]p<bus>s<slot>[f<function>][u<port>][..][c<config>][i<interface>]:: USB port number chain
All multi-function PCI devices will carry the [f<function>] number in the
device name, including the function 0 device.
When using PCI geography, The PCI domain is only prepended when it is not 0.
For USB devices the full chain of port numbers of hubs is composed. If the
name gets longer than the maximum number of 15 characters, the name is not
exported.
The usual USB configuration == 1 and interface == 0 values are suppressed.

NAME
----
dracut.modules - dracut modules
DESCRIPTION
-----------
dracut uses a modular system to build and extend the initramfs image. All
modules are located in _/usr/lib/dracut/modules.d_ or in _<git-src>/modules.d_.
The most basic dracut module is _99base_. In _99base_ the initial shell script
init is defined, which gets run by the kernel after initramfs loading. Although
you can replace init with your own version of _99base_, this is not encouraged.
Instead you should use, if possible, the hooks of dracut. All hooks, and the
point of time in which they are executed, are described in <<stages>>.
The main script, which creates the initramfs is dracut itsself. It parses all
arguments and sets up the directory, in which everything is installed. It then
executes all check, install, installkernel scripts found in the modules, which
are to be processed. After everything is installed, the install directory is
archived and compressed to the final initramfs image. All helper functions used
by check, install and installkernel are found in in the file _dracut-functions_.
These shell functions are available to all module installer (install,
installkernel) scripts, without the need to source _dracut-functions_.
A module can check the preconditions for install and installkernel with the
check script. Also dependencies can be expressed with check. If a module passed
check, install and installkernel will be called to install all of the necessary
files for the module. To split between kernel and non-kernel parts of the
installation, all kernel module related parts have to be in installkernel. All
other files found in a module directory are module specific and mostly are hook
scripts and udev rules.
[[stages]]
== Boot Process Stages
dracut modules can insert custom script at various points, to control the boot
process.
These hooks are plain directories containing shell scripts ending with ".sh",
which are sourced by init.
Common used functions are in _dracut-lib.sh_, which can be sourced by any script.
=== Hook: cmdline
The _cmdline_ hook is a place to insert scripts to parse the kernel command line
and prepare the later actions, like setting up udev rules and configuration
files.
In this hook the most important environment variable is defined: root. The
second one is rootok, which indicates, that a module claimed to be able to parse
the root defined. So for example, **root=**__iscsi:....__ will be claimed by the
iscsi dracut module, which then sets rootok.
=== Hook: pre-udev
This hook is executed right after the cmdline hook and a check if root and
rootok were set. Here modules can take action with the final root, and before
udev has been run.
=== Start Udev
Now udev is started and the logging for udev is setup.
=== Hook: pre-trigger
In this hook, you can set udev environment variables with **udevadm control
--property=KEY=_value_** or control the further execution of udev with
udevadm.
=== Trigger Udev
udev is triggered by calling udevadm trigger, which sends add events for all
devices and subsystems.
=== Main Loop
In the main loop of dracut loops until udev has settled and
all scripts in _initqueue/finished_ returned true.
In this loop there are three hooks, where scripts can be inserted
by calling /sbin/initqueue.
==== Initqueue
This hook gets executed every time a script is inserted here, regardless of the
udev state.
==== Initqueue settled
This hooks (initqueue/settled) gets executed every time udev has settled.
==== Initqueue timeout
This hooks (initqueue/timeout) gets executed, when the main loop counter becomes
half of the rd.retry counter.
==== Initqueue finished
This hook (initqueue/finished) is called after udev has settled and
if all scripts herein return 0 the main loop will be ended.
Abritary scripts can be added here, to loop in the
initqueue until something happens, which a dracut module wants to wait for.
=== Hook: pre-mount
Before the root device is mounted all scripts in the hook pre-mount are
executed. In some cases (e.g. NFS) the real root device is already mounted,
though.
=== Hook: mount
This hook is mainly to mount the real root device.
=== Hook: pre-pivot
This hook is called before cleanup hook, This is a good place for
actions other than cleanups which need to be called before pivot.
=== Hook: cleanup
This hook is the last hook and is called before init finally switches root to
the real root device. This is a good place to clean up and kill processes not
needed anymore.
=== Cleanup and switch_root
Init (or systemd) kills all udev processes, cleans up the environment,
sets up the arguments for the real init process and finally calls switch_root.
switch_root removes the whole filesystem hierarchy of the initramfs,
chroot()s to the real root device and calls /sbin/init with the specified
arguments.
To ensure all files in the initramfs hierarchy can be removed, all processes
still running from the initramfs should not have any open file descriptors left.
== Network Infrastructure
FIXME
== Writing a Module
A simple example module is _96insmodpost_, which modprobes a kernel module after
udev has settled and the basic device drivers have been loaded.
All module installation information is in the file module-setup.sh.
First we create a check() function, which just exits with 0 indicating that this
module should be included by default.
check():
----
return 0
----
The we create the install() function, which installs a cmdline hook with
priority number 20 called _parse-insmodpost.sh_. It also installs the
_insmodpost.sh_ script in _/sbin_.
install():
----
inst_hook cmdline 20 "$moddir/parse-insmodpost.sh"
inst_simple "$moddir/insmodpost.sh" /sbin/insmodpost.sh
----
The _pase-instmodpost.sh_ parses the kernel command line for a argument
rd.driver.post, blacklists the module from being autoloaded and installs the
hook _insmodpost.sh_ in the _initqueue/settled_.
_parse-insmodpost.sh_:
----
for p in $(getargs rd.driver.post=); do
echo "blacklist $p" >> /etc/modprobe.d/initramfsblacklist.conf
_do_insmodpost=1
done
[ -n "$_do_insmodpost" ] && /sbin/initqueue --settled --unique --onetime /sbin/insmodpost.sh
unset _do_insmodpost
----
_insmodpost.sh_, which is called in the _initqueue/settled_ hook will just
modprobe the kernel modules specified in all rd.driver.post kernel command line
parameters. It runs after udev has settled and is only called once (--onetime).
_insmodpost.sh_:
----
. /lib/dracut-lib.sh
for p in $(getargs rd.driver.post=); do
modprobe $p
done
----
=== module-setup.sh: check()
_check()_ is called by dracut to evaluate the inclusion of a dracut module in
the initramfs.
$hostonly:: If the $hostonly variable is set, then the module check() function
should be in "hostonly" mode, which means, that the check() should only return
0, if the module is really needed to boot this specific host.
check() should return with:
0:: Include the dracut module in the initramfs.
1:: Do not include the dracut module. The requirements are not fullfilled
(missing tools, etc.)
255:: Only include the dracut module, if another module requires it or if
explicitly specified in the config file or on the argument list.
=== module-setup.sh: depends()
The function depends() should echo all other dracut module names the module
depends on.
=== module-setup.sh: cmdline()
This function should print the kernel command line options needed to boot the
current machine setup. It should start with a space and should not print a
newline.
=== module-setup.sh: install()
The install() function is called to install everything non-kernel related.
To install binaries, scripts, and other files, you can use the functions
mentioned in <<creation>>.
To address a file in the current module directory, use the variable "$moddir".
=== module-setup.sh: installkernel()
In installkernel() all kernel related files should be installed. You can use all
of the functions mentioned in <<creation>> to install files.
=== [[creation]]Creation Functions
==== inst_multiple [-o] <file> [ <file> ...]
installs multiple binaries and files. If executables are specified without a
path, dracut will search the path PATH=/usr/sbin:/sbin:/usr/bin:/bin for the
binary. If the option "-o" is given as the first parameter, a missing file does
not lead to an error.
==== inst <src> [<dst>]
installs _one_ file <src> either to the same place in the initramfs or to an
optional <dst>.
==== inst_hook <hookdir> <prio> <src>
installs an executable/script <src> in the dracut hook <hookdir> with priority
<prio>.
==== inst_rules <udevrule> [ <udevrule> ...]
installs one ore more udev rules. Non-existant udev rules are reported, but do
not let dracut fail.
==== instmods <kernelmodule> [ <kernelmodule> ... ]
instmods should be used only in the installkernel() function.
instmods installs one or more kernel modules in the initramfs. <kernelmodule>
can also be a whole subsystem, if prefixed with a "=", like "=drivers/net/team".
instmods will not install the kernel module, if $hostonly is set and the kernel
module is not currently needed by any /sys/*...*/uevent MODALIAS.
To install a kernel module regardless of the hostonly mode use the form:
----
hostonly='' instmods <kernelmodule>

To create a initramfs image, the most simple command is:
----
# dracut
----
This will generate a general purpose initramfs image, with all possible
functionality resulting of the combination of the installed dracut modules and
system tools. The image is /boot/initramfs-_++<kernel version>++_.img and
contains the kernel modules of the currently active kernel with version
_++<kernel version>++_.
If the initramfs image already exists, dracut will display an error message, and
to overwrite the existing image, you have to use the --force option.
----
# dracut --force
----
If you want to specify another filename for the resulting image you would issue
a command like:
----
# dracut foobar.img
----
To generate an image for a specific kernel version, the command would be:
----
# dracut foobar.img 2.6.40-1.rc5.f20
----
A shortcut to generate the image at the default location for a specific kernel
version is:
----
# dracut --kver 2.6.40-1.rc5.f20
----
If you want to create lighter, smaller initramfs images, you may want to specify
the --hostonly or -H option. Using this option, the resulting image will
contain only those dracut modules, kernel modules and filesystems, which are
needed to boot this specific machine. This has the drawback, that you can't put
the disk on another controller or machine, and that you can't switch to another
root filesystem, without recreating the initramfs image. The usage of the
--hostonly option is only for experts and you will have to keep the broken
pieces. At least keep a copy of a general purpose image (and corresponding
kernel) as a fallback to rescue your system.
=== Inspecting the Contents
To see the contents of the image created by dracut, you can use the lsinitrd
tool.
----
# lsinitrd | less
----
To display the contents of a file in the initramfs also use the lsinitrd tool:
----
# lsinitrd -f /etc/ld.so.conf
include ld.so.conf.d/*.conf
----
=== Adding dracut Modules
Some dracut modules are turned off by default and have to be activated manually.
You can do this by adding the dracut modules to the configuration file
_/etc/dracut.conf_ or _/etc/dracut.conf.d/myconf.conf_. See *dracut.conf*(5).
You can also add dracut modules on the command line
by using the -a or --add option:
----
# dracut --add bootchart initramfs-bootchart.img
----
To see a list of available dracut modules, use the --list-modules option:
----
# dracut --list-modules
----
=== Omitting dracut Modules
Sometimes you don't want a dracut module to be included for reasons of speed,
size or functionality. To do this, either specify the omit_dracutmodules
variable in the _dracut.conf_ or _/etc/dracut.conf.d/myconf.conf_ configuration
file (see *dracut.conf*(5)), or use the -o or --omit option
on the command line:
----
# dracut -o "multipath lvm" no-multipath-lvm.img
----
=== Adding Kernel Modules
If you need a special kernel module in the initramfs, which is not
automatically picked up by dracut, you have the use the --add-drivers option
on the command line or the drivers vaiable in the _/etc/dracut.conf_
or _/etc/dracut.conf.d/myconf.conf_ configuration file (see *dracut.conf*(5)):
----
# dracut --add-drivers mymod initramfs-with-mymod.img
----
=== Boot parameters
An initramfs generated without the "hostonly" mode, does not contain any system
configuration files (except for some special exceptions), so the configuration
has to be done on the kernel command line. With this flexibility, you can easily
boot from a changed root partition, without the need to recompile the initramfs
image. So, you could completly change your root partition (move it inside a md
raid with encryption and LVM on top), as long as you specify the correct
filesystem LABEL or UUID on the kernel command line for your root device, dracut
will find it and boot from it.
The kernel command line usually can be configured in _/boot/grub/grub.conf_ or
_/boot/grub2/grub.cfg_, if grub is your bootloader and it also can be edited in
the real boot process in the grub menu.
The kernel command line can also be provided by the dhcp server with the
root-path option. See <<NetworkBoot>>.
For a full reference of all kernel command line parameters,
see *dracut.cmdline*(5).
To get a quick start for the suitable kernel command line on your system,
use the __--print-cmdline__ option:
----
# dracut --print-cmdline
root=UUID=8b8b6f91-95c7-4da2-831b-171e12179081 rootflags=rw,relatime,discard,data=ordered rootfstype=ext4
----
==== Specifying the root Device
This is the only option dracut really needs to boot from your root partition.
Because your root partition can live in various environments, there are a lot of
formats for the root= option. The most basic one is root=_++<path to device
node>++_:
----
root=/dev/sda2
----
Because device node names can change, dependent on the drive ordering, you are
encouraged to use the filesystem identifier (UUID) or filesystem label (LABEL)
to specify your root partition:
----
root=UUID=19e9dda3-5a38-484d-a9b0-fa6b067d0331
----
or
----
root=LABEL=myrootpartitionlabel
----
To see all UUIDs or LABELs on your system, do:
----
# ls -l /dev/disk/by-uuid
----
or
----
# ls -l /dev/disk/by-label
----
If your root partition is on the network see <<NetworkBoot>>.
==== Keyboard Settings
If you have to input passwords for encrypted disk volumes, you might want to set
the keyboard layout and specify a display font.
A typical german kernel command would contain:
----
rd.vconsole.font=latarcyrheb-sun16 rd.vconsole.keymap=de-latin1-nodeadkeys rd.locale.LANG=de_DE.UTF-8
----
Setting these options can override the setting stored on your system, if you use
a modern init system, like systemd.
==== Blacklisting Kernel Modules
Sometimes it is required to prevent the automatic kernel module loading of a
specific kernel module. To do this, just add rd.blacklist=_++<kernel module
name>++_, with _++<kernel module name>++_ not containing the _.ko_
suffix, to the kernel command line. For example:
----
rd.driver.blacklist=mptsas rd.driver.blacklist=nouveau
----
The option can be specified multiple times on the kernel command line.
==== Speeding up the Boot Process
If you want to speed up the boot process, you can specify as much information
for dracut on the kernel command as possible. For example, you can tell dracut,
that you root partition is not on a LVM volume or not on a raid partition, or
that it lives inside a specific crypto LUKS encrypted volume. By default, dracut
searches everywhere. A typical dracut kernel command line for a plain primary or
logical partition would contain:
----
rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0
----
This turns off every automatic assembly of LVM, MD raids, DM raids and
crypto LUKS.
Of course, you could also omit the dracut modules in the initramfs creation
process, but then you would lose the posibility to turn it on on demand.
[[Injecting]]
=== Injecting custom Files
To add your own files to the initramfs image, you have several possibilities.
The --include option let you specify a source path and a target path.
For example
----
# dracut --include cmdline-preset /etc/cmdline.d/mycmdline.conf initramfs-cmdline-pre.img
----
will create an initramfs image, where the file cmdline-preset will be copied
inside the initramfs to _/etc/cmdline.d/mycmdline.conf_. --include can only
be specified once.
----
# mkdir -p rd.live.overlay/etc/cmdline.d
# mkdir -p rd.live.overlay/etc/conf.d
# echo "ip=auto" >> rd.live.overlay/etc/cmdline.d/mycmdline.conf
# echo export FOO=testtest >> rd.live.overlay/etc/conf.d/testvar.conf
# echo export BAR=testtest >> rd.live.overlay/etc/conf.d/testvar.conf
# tree rd.live.overlay/
rd.live.overlay/
`-- etc
|-- cmdline.d
| `-- mycmdline.conf
`-- conf.d
`-- testvar.conf
# dracut --include rd.live.overlay / initramfs-rd.live.overlay.img
----
This will put the contents of the rd.live.overlay directory into the root of the
initramfs image.
The --install option let you specify several files, which will get installed in
the initramfs image at the same location, as they are present on initramfs
creation time.
----
# dracut --install 'strace fsck.ext3 ssh' initramfs-dbg.img
----
This will create an initramfs with the strace, fsck.ext3 and ssh executables,
together with the libraries needed to start those. The --install option can be
specified multiple times.
[[NetworkBoot]]
=== Network Boot
If your root partition is on a network drive, you have to have the network
dracut modules installed to create a network aware initramfs image.
On a Red Hat Enterprise Linux or Fedora system, this means, you have to install
the _dracut-network_ rpm package:
----
# yum install dracut-network
----
The resulting initramfs image can be served by a boot manager residing on your
local hard drive or it can be served by a PXE/TFTP server.
How to setup your PXE/TFTP server can be found in the
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/[Red
Hat Enterprise Linux Storage Administration Guide].
If you specify ip=auto on the kernel command line, then dracut asks a dhcp
server about the ip adress for the machine. The dhcp server can also serve an
additional root-path, which will set the root device for dracut. With this
mechanism, you have static configuration on your client machine and a
centralized boot configuration on your TFTP/DHCP server. If you can't pass a
kernel command line, then you can inject _/etc/cmdline.d/mycmdline.conf_, with a
method described in <<Injecting>>.
==== Reducing the Image Size
To reduce the size of the initramfs, you should create it with by ommitting all
dracut modules, which you know, you don't need to boot the machine.
You can also specify the exact dracut and kernel modules to produce a very tiny
initramfs image.
For example for a NFS image, you would do:
----
# dracut -m "nfs network base" initramfs-nfs-only.img
----
Then you would boot from this image with your target machine and reduce the size
once more by creating it on the target machine with the --host-only option:
----
# dracut -m "nfs network base" --host-only initramfs-nfs-host-only.img
----
This will reduce the size of the initramfs image significantly.
== Troubleshooting
If the boot process does not succeed, you have several options to debug the
situation. Some of the basic operations are covered here. For more information
you should also visit:
http://fedoraproject.org/wiki/How_to_debug_Dracut_problems
[[identifying-your-problem-area]]
=== Identifying your problem area
. Remove ''rhgb'' and ''quiet'' from the kernel command line
. Add ''rd.shell'' to the kernel command line. This will present a shell should
dracut be unable to locate your root device
. Add ''rd.shell rd.debug log_buf_len=1M'' to the kernel command line so that
dracut shell commands are printed as they are executed
. The file /run/initramfs/rdsosreport.txt is generated,
which contains all the logs and the output of all significant tools, which are
mentioned later.
If you want to save that output, simply mount /boot by hand or insert an USB
stick and mount that. Then you can store the output for later inspection.
[[information-to-include-in-your-report]]
=== Information to include in your report
[[all-bug-reports]]
==== All bug reports
In all cases, the following should be mentioned and attached to your bug report:
* The exact kernel command-line used. Typically from the bootloader
configuration file (e.g. _/etc/grub.conf_) or from _/proc/cmdline_.
* A copy of your disk partition information from _/etc/fstab_, which might be
obtained booting an old working initramfs or a rescue medium.
* Turn on dracut debugging (see _the 'debugging dracut' section_), and attach
the file /run/initramfs/rdsosreport.txt.
* If you use a dracut configuration file, please include _/etc/dracut.conf_ and
all files in _/etc/dracut.conf.d/*.conf_
[[network-root-device-related-problems]]
==== Network root device related problems
This section details information to include when experiencing problems on a
system whose root device is located on a network attached volume (e.g. iSCSI,
NFS or NBD). As well as the information from <<all-bug-reports>>, include the
following information:
* Please include the output of
+
----
# /sbin/ifup <interfacename>
# ip addr show
----
[[debugging-dracut]]
=== Debugging dracut
[[configure-a-serial-console]]
==== Configure a serial console
Successfully debugging dracut will require some form of console
logging during the system boot. This section documents configuring a
serial console connection to record boot messages.
. First, enable serial console output for both the kernel and the bootloader.
. Open the file _/etc/grub.conf_ for editing. Below the line ''timeout=5'', add
the following:
+
----
serial --unit=0 --speed=9600
terminal --timeout=5 serial console
----
+
. Also in _/etc/grub.conf_, add the following boot arguemnts to the ''kernel''
line:
+
----
console=tty0 console=ttyS0,9600
----
+
. When finished, the _/etc/grub.conf_ file should look similar to the example
below.
+
----
default=0
timeout=5
serial --unit=0 --speed=9600
terminal --timeout=5 serial console
title Fedora (2.6.29.5-191.fc11.x86_64)
root (hd0,0)
kernel /vmlinuz-2.6.29.5-191.fc11.x86_64 ro root=/dev/mapper/vg_uc1-lv_root console=tty0 console=ttyS0,9600
initrd /dracut-2.6.29.5-191.fc11.x86_64.img
----
+
. More detailed information on how to configure the kernel for console output
can be found at
http://www.faqs.org/docs/Linux-HOWTO/Remote-Serial-Console-HOWTO.html#CONFIGURE-KERNEL.
. Redirecting non-interactive output
+
--
NOTE: You can redirect all non-interactive output to _/dev/kmsg_ and the kernel
will put it out on the console when it reaches the kernel buffer by doing
----
# exec >/dev/kmsg 2>&1 </dev/console
----
--
[[using-the-dracut-shell]]
==== Using the dracut shell
dracut offers a shell for interactive debugging in the event dracut fails to
locate your root filesystem. To enable the shell:
. Add the boot parameter ''rd.shell'' to your bootloader configuration file
(e.g. _/etc/grub.conf_)
. Remove the boot arguments ''rhgb'' and ''quiet''
+
A sample _/etc/grub.conf_ bootloader configuration file is listed below.
+
----
default=0
timeout=5
serial --unit=0 --speed=9600
terminal --timeout=5 serial console
title Fedora (2.6.29.5-191.fc11.x86_64)
root (hd0,0)
kernel /vmlinuz-2.6.29.5-191.fc11.x86_64 ro root=/dev/mapper/vg_uc1-lv_root console=tty0 rd.shell
initrd /dracut-2.6.29.5-191.fc11.x86_64.img
----
+
. If system boot fails, you will be dropped into a shell as seen in the example
below.
+
----
No root device found
Dropping to debug shell.
#
----
+
. Use this shell prompt to gather the information requested above
(see <<all-bug-reports>>).
[[accessing-the-root-volume-from-the-dracut-shell]]
==== Accessing the root volume from the dracut shell
From the dracut debug shell, you can manually perform the task of locating and
preparing your root volume for boot. The required steps will depend on how your
root volume is configured. Common scenarios include:
* A block device (e.g. _/dev/sda7_)
* A LVM logical volume (e.g. _/dev/VolGroup00/LogVol00_)
* An encrypted device
(e.g. _/dev/mapper/luks-4d5972ea-901c-4584-bd75-1da802417d83_)
* A network attached device
(e.g. _netroot=iscsi:@192.168.0.4::3260::iqn.2009-02.org.example:for.all_)
The exact method for locating and preparing will vary. However, to continue with
a successful boot, the objective is to locate your root volume and create a
symlink _/dev/root_ which points to the file system. For example, the following
example demonstrates accessing and booting a root volume that is an encrypted
LVM Logical volume.
. Inspect your partitions using parted
+
----
# parted /dev/sda -s p
Model: ATA HTS541060G9AT00 (scsi)
Disk /dev/sda: 60.0GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 32.3kB 10.8GB 107MB primary ext4 boot
2 10.8GB 55.6GB 44.7GB logical lvm
----
+
. You recall that your root volume was a LVM logical volume. Scan and activate
any logical volumes.
+
----
# lvm vgscan
# lvm vgchange -ay
----
+
. You should see any logical volumes now using the command blkid:
+
----
# blkid
/dev/sda1: UUID="3de247f3-5de4-4a44-afc5-1fe179750cf7" TYPE="ext4"
/dev/sda2: UUID="Ek4dQw-cOtq-5MJu-OGRF-xz5k-O2l8-wdDj0I" TYPE="LVM2_member"
/dev/mapper/linux-root: UUID="def0269e-424b-4752-acf3-1077bf96ad2c" TYPE="crypto_LUKS"
/dev/mapper/linux-home: UUID="c69127c1-f153-4ea2-b58e-4cbfa9257c5e" TYPE="ext3"
/dev/mapper/linux-swap: UUID="47b4d329-975c-4c08-b218-f9c9bf3635f1" TYPE="swap"
----
+
. From the output above, you recall that your root volume exists on an encrypted
block device. Following the guidance disk encryption guidance from the
Installation Guide, you unlock your encrypted root volume.
+
----
# UUID=$(cryptsetup luksUUID /dev/mapper/linux-root)
# cryptsetup luksOpen /dev/mapper/linux-root luks-$UUID
Enter passphrase for /dev/mapper/linux-root:
Key slot 0 unlocked.
----
+
. Next, make a symbolic link to the unlocked root volume
+
----
# ln -s /dev/mapper/luks-$UUID /dev/root
----
+
. With the root volume available, you may continue booting the system by exiting
the dracut shell
+
----
# exit
----
[[additional-dracut-boot-parameters]]
==== Additional dracut boot parameters
For more debugging options, see *dracut.cmdline*(7).
[[debugging-dracut-on-shutdown]]
==== Debugging dracut on shutdown
To debug the shutdown sequence on systemd systems, you can _rd.break_
on _pre-shutdown_ or _shutdown_.
To do this from an already booted system:
----
# mkdir -p /run/initramfs/etc/cmdline.d
# echo "rd.break=pre-shutdown" > /run/initramfs/etc/cmdline.d/debug.conf
# touch /run/initramfs/.need_shutdown
----
This will give you a dracut shell after the system pivot'ed back in the
initramfs.

MKINITRD(8)
===========
:doctype: manpage
:man source: dracut
:man manual: dracut
NAME
----
mkinitrd-suse - is a compat wrapper, which calls dracut to generate an initramfs
SYNOPSIS
--------
*mkinitrd* ['OPTION...']
DESCRIPTION
-----------
*mkinitrd* creates an initramfs image <initrd-image> for the kernel with
version <kernel-version> by calling *dracut*.
[IMPORTANT]
This version of mkinitrd is provided for compability with older
versions of mkinitrd. If a more fine grained control over the
resulting image is needed, *dracut* should be called directly.
OPTIONS
-------
**-R, --version**::
print info about the version
**-k** _<kernel_list>_::
List of kernel images for which initrd files are created (relative
to _boot_dir_), defaults to _vmlinux_ on ppc/ppc64, _image_ on s390/s390x
and _vmlinuz_ for everything else.
**-i** _<initrd_list>_::
List of file names (relative to _boot_dir_) for the initrd; positions
have to match the _kernel_list_. Defaults to _initrd_.
**-m** _<module_list>_::
Modules to include in initrd, defaults to _INITRD_MODULES_ variable
in */etc/sysconfig/kernel*.
**-f** _<feature_list>_::
Features to be enabled for the initrd. In general mkinitrd
configures the initrd for the root device it is started from. With
this option additional feature can be enabled.
**-b** _<bootdir>_::
Boot directory, defaults to */boot*, where the initrd is created.
**-d** _<root_device>_::
Root device, defaults to the device from which the root_dir is
mounted; overwrites the rootdev enviroment variable if set
**-s** _<size>_::
Add splash animation and bootscreen to initrd.
**-D** _<interface>::
Run dhcp on the specified interface (for example "eth0").
**-I** _<interface>::
Configure the specified interface statically.
**-a** _<acpi_dsdt>::
Attach compiled ACPI DSDT (Differentiated System Description Table)
to initrd. This replaces the DSDT of the BIOS. Defaults to the
_ACPI_DSDT_ variable in */etc/sysconfig/kernel*.
**-M** _<map>::
System.map file to use.
**-B**::
Dont run the *update-bootloader(8)* script after the initrd(s) have
been created. This is useful if you call mkinitrd(8) for anything
else than the running system.
**-A**::
Create a so called "monster initrd" which includes all available
features and modules.
**-v, --verbose**::
increase verbosity level
**-L**::
Disable logging to _/var/log/YaST2/mkinitrd.log_. This is useful for
testing if you dont want to clutter the system log.
**--force**::
overwrite existing initramfs file.
**--help**::
print a help message and exit.
AVAILABILITY
------------
The mkinitrd command is part of the dracut package and is available from
link:$$https://dracut.wiki.kernel.org$$[https://dracut.wiki.kernel.org]
