6c2905c425 LVM/DM rules in dracut 
I've looked at the LVM rules used in dracut just recently
and it needs fixing - we should react to change events only
for DM devices, so we have to skip vol_id/blkid call on ADD:

KERNEL=="dm-[0-9]*", ACTION=="add", GOTO="lvm_end"

Also, MD devices have their own rules, where vol_id/blkid
is called and where the symlinks are created (when looking
into raw initrd, this is in  64-md-raid.rules).

Also, if those rules are meant to be for DM devices only,
maybe we should skip symlink creation for the other devices
there, to keep the rules clean and straightforward. I think
we shouldn't create/recreate symlinks for non-dm devices in
LVM/DM rules (..should be in appropriate rules for that type
of device):

KERNEL!="dm-[0-9]*", GOTO="lvm_end"

dracut-032
==========
- add parameter --print-cmdline
This prints the kernel command line parameters for the current disk
layout.
$ dracut --print-cmdline
rd.luks.uuid=luks-e68c8906-6542-4a26-83c4-91b4dd9f0471
rd.lvm.lv=debian/root rd.lvm.lv=debian/usr root=/dev/mapper/debian-root

rootfstype=ext4
- dracut.sh: add --persistent-policy option and persistent_policy conf option
--persistent-policy <policy>:
Use <policy> to address disks and partitions.
<policy> can be any directory name found in /dev/disk.
E.g. "by-uuid", "by-label"
- dracut now creates the initramfs without udevadm
that means the udev database does not have to populated
and the initramfs can be built in a chroot with
/sys /dev /proc mounted

- if $libdirs is unset, fall back to ld.so.cache paths
- always assemble /usr device in initramfs
- bash module added (disable it, if you really want dash)
- continue to boot, if the main loop times out, in systemd mode
- removed inst*() shell pure versions, dracut-install binary is in charge now
- fixed ifcfg file generation for vlan

- dracut makes use of native systemd initrd units
- added hooks for new-kernel-pkg and kernel-install
- hostonly is now default for fedora
- comply with the BootLoaderSpec paths
http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec

- use -D_FILE_OFFSET_BITS=64 to build dracut-install
dracut-026
==========
- introduce /usr/lib/dracut/dracut.conf.d/ drop-in directory
/usr/lib/dracut/dracut.conf.d/*.conf can be overwritten by the same
filenames in /etc/dracut.conf.d.
Packages should use /usr/lib/dracut/dracut.conf.d rather than
/etc/dracut.conf.d for drop-in configuration files.
/etc/dracut.conf and /etc/dracut.conf.d belong to the system administrator.
- uses systemd-198 native initrd units
- totally rely on the fstab-generator in systemd mode for block devices
- dracut systemd now uses dracut.target rather than basic.target
- dracut systemd services optimize themselves away
- fixed hostonly parameter generation
- turn off curl globbing (fixes IPv6)
- modify the udev rules on install and not runtime time
- enable initramfs building without kernel modules (fixed regression)
- in the initqueue/timeout,
reset the main loop counter, as we see new udev events or initqueue/work
- fixed udev rule installation
dracut-025
==========
- do not strip signed kernel modules
- add sosreport script and generate /run/initramfs/sosreport.txt
- make short uuid specification for allow-discards work
- turn off RateLimit for the systemd journal
- fixed MAC address assignment
- add systemd checkisomd5 service
- splitout drm kernel modules from plymouth module
- add 'swapoff' to initramfs to fix shutdown/reboot
- add team device support
- add pre-shutdown hook
- kill all processes in shutdown and report remaining ones
- "--device" changed to "--add-device" and "add_device=" added for conf files
- add memory usage trace to different hook points
- cope with optional field #7 in /proc/self/mountinfo
- lots of small bugfixes
dracut-024
==========
- new dracut option "--device"
- new dracut kernel command line options "rd.auto"
- new dracut kernel command line options "rd.noverifyssl"
- new dracut option "--kernel-cmdline" and "kernel_cmdline" option for default parameters
- fixes for systemd and crypto
- fix for kexec in shutdown, if not included in initramfs
- create the initramfs non-world readable
- prelink/preunlink in the initramfs
- strip binaries in the initramfs by default now
- various FIPS fixes
- various dracut-install fixes
dracut-023
==========
- resume from hibernate fixes
- -N option for --no-hostonly
- support for systemd crypto handling
- new dracut module "crypt-loop"
- deprecate the old kernel command line options
- more documentation
- honor CFLAGS for dracut-install build
- multipath fixes
- / is mounted according to rootflags parameter but forced ro at first.
Later it is remounted according to /etc/fstab + rootflags parameter
and "ro"/"rw".
- support for xfs / reiserfs separate journal device
- new "ro_mnt" option to force ro mount of / and /usr
- root on cifs support
- dracut-install: fixed issue for /var/tmp containing a symlink
- only lazy resolve with ldd, if the /var/tmp partition is not mounted with "noexec"
- i18n: fixed inclusion of "include" keymaps
dracut-022
==========
- fixed host-only kernel module bug
dracut-021
==========
- fixed systemd in the initramfs (requires systemd >= 187)
- dracut-install: massive speedup with /var on the same filesystem with COW copy
- dracut-install: moved to /usr/lib/dracut until it becomes a general purpose tool
- new options: "rd.usrmount.ro" and "rd.skipfsck"
- less mount/umount
- apply "ro" on the kernel command line also to /usr
- mount according to fstab, if neither "ro" or "rw" is specified
- skip fsck for xfs and btrfs. remount is enough
- give emergency_shell if /usr mount failed
- dracut now uses getopt:
* options can be position independent now!!
* we can now use --option=<arg>
- added option "--kver=<kernel-version>", and the image location can be omitted
# dracut --kver 3.5.0-0.rc7.git1.2.fc18.x86_64
- dracut.sh: for --include copy also the symbolic links
- man pages: lsinitrd and mkinitrd added
- network: We do not support renaming in the kernel namespace anymore (as udev does
that not anymore). So, if a user wants to use ifname, he has to rename
to a custom namespace. "eth[0-9]+" is not allowed anymore. !!!!!
- resume: moved the resume process to the initqueue.
This should prevent accidently mounting the root file system.
- testsuite: add support for: make V=1 TESTS="01 20 40" check
$ sudo make V=1 clean check
now runs the testsuite in verbose mode
$ sudo make TESTS="01 20 40" clean check
now only runs the 01, 20 and 40 tests.
dracut-020
==========
- changed rd.dasd kernel parameter
- arm kernel modules added to kernel-modules
- make udevdir systemdutildir systemdsystemunitdir global vars
your distribution should ship those settings in
/etc/dracut.conf.d/01-distro.conf
see dracut.conf.d/fedora.conf.example
- kernel modules are now only handled with /sys/modules and modules.dep
- systemd fixups
- mdraid: wait for md devices to be clean, before shutdown
- ifup fixed for ipv6
- add PARTUUID as root=PARTUUID=<partition uuid> parameter
- fixed instmods() return code and set pipefail globally
- add 04watchdog dracut module
- dracut-shutdown.service: fixed ordering to be before shutdown.target
- make use of "ln -r" instead of shell functions, if new coreutils is installed
- network: support vlan tagged bonding
- new dracut module qemu and qemu-net to install all kernel driver
- fs-lib/fs-lib.sh: removed test mounting of btrfs and xfs

For "--kernel-only" all installkernel scripts of the specified
modules are used, regardless of any checks, so that all modules

modules and one without. So if the kernel changes, you only have
to replace one image.
Grub and the kernel can handle multiple images, so grub entry can
look like this:

- dracut-install parse LD_SHOW_AUXV="" AT_PLATFORM for lib install
CODE TODO
- document more functions
- make function vars local, and prefix with "_"
Future Enhancement Requests
- run ssh server to enter crypto password or perform debugging (supported by debian)
- https://bugzilla.redhat.com/show_bug.cgi?id=524727 - dracut + encrypted root + networking
See https://sourceforge.net/apps/trac/dracut/wiki/TODO

## @brief Logging facility module for dracut both at build- and boot-time.
#
# @section intro Introduction
#
# The logger takes a bit from Log4j philosophy. There are defined 6 logging
# levels:
# - TRACE (6)
# The TRACE Level designates finer-grained informational events than the
# DEBUG.
# - DEBUG (5)
# The DEBUG Level designates fine-grained informational events that are most
# useful to debug an application.
# - INFO (4)
# The INFO level designates informational messages that highlight the
# progress of the application at coarse-grained level.
# - WARN (3)
# The WARN level designates potentially harmful situations.
# - ERROR (2)
# The ERROR level designates error events that might still allow the
# application to continue running.
# - FATAL (1)
# The FATAL level designates very severe error events that will presumably
# lead the application to abort.
# Descriptions are borrowed from Log4j documentation:
# http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html
#
# @section usage Usage
#
# First of all you have to start with dlog_init() function which initializes
# required variables. Don't call any other logging function before that one!
# If you're ready with this, you can use following functions which corresponds
# clearly to levels listed in @ref intro Introduction. Here they are:
# - dtrace()
# - ddebug()
# - dinfo()
# - dwarn()
# - derror()
# - dfatal()
# They take all arguments given as a single message to be logged. See dlog()
# function for details how it works. Note that you shouldn't use dlog() by
# yourself. It's wrapped with above functions.
#
# @see dlog_init() dlog()
#
# @section conf Configuration
#
# Logging is controlled by following global variables:
# - @var stdloglvl - logging level to standard error (console output)
# - @var sysloglvl - logging level to syslog (by logger command)
# - @var fileloglvl - logging level to file
# - @var kmsgloglvl - logging level to /dev/kmsg (only for boot-time)
# - @var logfile - log file which is used when @var fileloglvl is higher
# than 0
# and two global variables: @var maxloglvl and @var syslogfacility which <b>must
# not</b> be overwritten. Both are set by dlog_init(). @var maxloglvl holds
# maximum logging level of those three and indicates that dlog_init() was run.
# @var syslogfacility is set either to 'user' (when building initramfs) or
# 'daemon' (when booting).
#
# Logging level set by the variable means that messages from this logging level
# and above (FATAL is the highest) will be shown. Logging levels may be set
# independently for each destination (stderr, syslog, file, kmsg).
#
# @see dlog_init()
## @brief Initializes dracut Logger.
#
# @retval 1 if something has gone wrong
# @retval 0 on success.
#
# @note This function need to be called before any other from this file.
#
# If any of the variables is not set, this function set it to default:
# - @var stdloglvl = 4 (info)
# - @var sysloglvl = 0 (no logging)
# - @var fileloglvl is set to 4 when @var logfile is set too, otherwise it's
# - @var kmsgloglvl = 0 (no logging)
# set to 0
#
# @warning Function sets global variables @var maxloglvl and @syslogfacility.
# See file doc comment for details.

.SH KERNEL COMMAND LINE
The root filesystem used by the kernel is specified in the boot configuration
file, as always. The traditional \fBroot=/dev/hda1\fR style device
specification is allowed. If a label is used, as in \fBroot=LABEL=rootPart\fR
the initrd will search all available devices for an ext2 or ext3 filesystem
with the appropriate label, and mount that device as the root filesystem.
\fBroot=UUID=uuidnumber\fR will mount the partition with that UUID as the
root filesystem.
.SH Standard
.TP
.B init=<path to real init>
.TP
.B root=<path to blockdevice>

.SH DASD
.TP
.B dasd=....
same syntax as the kernel module parameter (s390 only)
.SH DHCP
.TP
.B root=dhcp
get IP from dhcp server, root-path option from dhcp specifies root location
.SH NFS
.TP
.B root=[<server-ip>:]<root-dir>[:<nfs-options>]
mount nfs share from <server-ip>:/<root-dir>, if no server-ip is given,
use dhcp next_server.
NFS options can be appended with the prefix "." or ","
.TP
.B root=nfs:[<server-ip>:]<root-dir>[:<nfs-options>]
.TP
.B root=nfs4:[<server-ip>:]<root-dir>[:<nfs-options>]
.TP
.B root=dhcp
root=dhcp alone directs initrd to look at the DHCP root-path where NFS
options can be specified.
root-path=<server-ip>:<root-dir>[,<nfs-options>]
root-path=nfs:<server-ip>:<root-dir>[,<nfs-options>]
root-path=nfs4:<server-ip>:<root-dir>[,<nfs-options>]

This is supported by dracut but not recommended.
.SH iSCSI
.TP
.B root=iscsi:[username:password[reverse:password]@][<servername>]:[<protocol>]:[<port>]:[<LUN>]:<targetname>
protocol defaults to "6", LUN defaults to "0".
If the "servername" field is provided by BOOTP or DHCP, then that
field is used in conjunction with other associated fields to contact
the boot server in the Boot stage (Section 7). However, if the
"servername" field is not provided, then the "targetname" field is
then used in the Discovery Service stage in conjunction with other
associated fields.

NAME
----
dracut - low-level tool for generating an initramfs image
SYNOPSIS
--------
*dracut* ['OPTION...'] [<image> [_<kernel version>_]]
DESCRIPTION
-----------
Create an initramfs <image> for the kernel with the version <kernel version>.
If <kernel version> is omitted, then the version of the actual running
kernel is used. If <image> is omitted or empty, then the default location
/boot/initramfs-<kernel version>.img is used.
dracut creates an initial image used by the kernel for preloading the block
device modules (such as IDE, SCSI or RAID) which are needed to access the root
filesystem, mounting the root filesystem and booting into the real system.
At boot time, the kernel unpacks that archive into RAM disk, mounts and uses it
as initial root file system. All finding of the root device happens in this
early userspace.
For a complete list of kernel command line options see *dracut.cmdline*(7).
If you are dropped to an emergency shell, while booting your initramfs,
the file _/run/initramfs/rdsosreport.txt_ is created, which can be safed to a
(to be mounted by hand) partition (usually /boot) or a USB stick.
Additional debugging info can be produced by adding **rd.debug** to the kernel command line.
_/run/initramfs/rdsosreport.txt_ contains all logs and the output of some tools.
It should be attached to any report about dracut problems.
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.

Compress the generated initramfs using the passed compression program. If
you pass it just the name of a compression program, it will call that
program with known-working arguments. If you pass a quoted string with
arguments, it will be called with exactly those arguments. Depending on what
you pass, this may result in an initramfs that the kernel cannot decompress.

DRACUT.CMDLINE(7)
=================
:doctype: manpage

:man manual: dracut
NAME
----
dracut.cmdline - dracut kernel command line options
DESCRIPTION
-----------
The root device used by the kernel is specified in the boot configuration
file on the kernel command line, as always.
The traditional _root=/dev/sda1_ style device specification is allowed, but not
encouraged. The root device should better be identified by LABEL or UUID. If a
label is used, as in _root=LABEL=<label_of_root>_ the initramfs will search all
available devices for a filesystem with the appropriate label, and mount that
device as the root filesystem. _root=UUID=<uuidnumber>_ will mount the partition
with that UUID as the root filesystem.
In the following all kernel command line parameters, which are processed by
dracut, are described.
"rd.*" parameters mentioned without "=" are boolean parameters. They can be
turned on/off by setting them to {0|1}. If the assignment with "=" is missing
"=1" is implied. For example _rd.info_ can be turned off with _rd.info=0_ or
turned on with _rd.info=1_ or _rd.info_. The last value in the kernel command
line is the value, which is honored.
Standard
~~~~~~~~
**init=**_<path to real init>_::
specify the path to the init programm to be started after the initramfs has
finished
**root=**_<path to blockdevice>_::
specify the block device to use as the root filesystem.
+
E.g.:
+
----
root=/dev/sda1
root=/dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0-part1
root=/dev/disk/by-label/Root
root=LABEL=Root
root=/dev/disk/by-uuid/3f5ad593-4546-4a94-a374-bcfb68aa11f7
root=UUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7
root=PARTUUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7
----
**rootfstype=**_<filesystem type>_:: "auto" if not specified, e.g.:
+
----
rootfstype=ext3
----
**rootflags=**_<mount options>_::
specify additional mount options for the root filesystem. If not set,
_/etc/fstab_ of the real root will be parsed for special mount options and
mounted accordingly.
**ro**::
force mounting _/_ and _/usr_ (if it is a separate device) read-only. If
none of ro and rw is present, both are mounted according to _/etc/fstab_.
**rw**::
force mounting _/_ and _/usr_ (if it is a separate device) read-write.
See also ro option.
**rd.auto** **rd.auto=1**::
enable autoassembly of special devices like cryptoLUKS, dmraid, mdraid or lvm.
Default is off as of dracut version >= 024.
**rd.fstab=0**::
do not honor special mount options for the root filesystem found in
_/etc/fstab_ of the real root.
**resume=**_<path to resume partition>_::
resume from a swap partition
+
E.g.:
+
----
resume=/dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0-part1
resume=/dev/disk/by-uuid/3f5ad593-4546-4a94-a374-bcfb68aa11f7
resume=UUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7
----
**rd.skipfsck**::
skip fsck for rootfs and _/usr_. If you're mounting _/usr_ read-only and
the init system performs fsck before remount, you might want to use this
option to avoid duplication.
Misc
~~~~
**rd.driver.blacklist=**_<drivername>[,<drivername>,...]_::
do not load kernel module <drivername>. This parameter can be specified
multiple times.
**rd.driver.pre=**_<drivername>[,<drivername>,...]_::
force loading kernel module <drivername>. This parameter can be specified
multiple times.
**rd.driver.post=**_<drivername>[,<drivername>,...]_::
force loading kernel module <drivername> after all automatic loading modules
have been loaded. This parameter can be specified multiple times.
**rd.retry=**_<seconds>_::
specify how long dracut should wait for devices to appear.
The default is 30 seconds. After 2/3 of the time, degraded raids are force
started. If you have hardware, which takes a very long time to announce its
drives, you might want to extend this value.
**rd.noverifyssl**::
accept self-signed certificates for ssl downloads.
**rd.ctty=**_<terminal device>_**::
specify the controlling terminal for the console.
This is useful, if you have multiple "console=" arguments.

Debug
~~~~~
If you are dropped to an emergency shell, the file _/run/initramfs/rdsosreport.txt_ is created,
which can be safed to a (to be mounted by hand) partition (usually /boot) or a USB stick.
Additional debugging info can be produced by adding **rd.debug** to the kernel command line.
_/run/initramfs/rdsosreport.txt_ contains all logs and the output of some tools.
It should be attached to any report about dracut problems.
**rd.info**::
print informational output though "quiet" is set
**rd.shell**::
allow dropping to a shell, if root mounting fails
**rd.debug**::
set -x for the dracut shell.
If systemd is active in the initramfs, all output is logged to the systemd journal,
which you can inspect with "journalctl -ab".
If systemd is not active, the logs are written to dmesg and _/run/initramfs/init.log_.
If "quiet" is set, it also logs to the console.

_/etc/vconsole.conf_ in the initramfs; e.g.:
+
----

see description of '-m' parameter in setfont manual; taken from consoletrans
directory; will be written as FONT_MAP to _/etc/vconsole.conf_ in the
initramfs
**vconsole.font.unimap=**_<unicode table base file name>_::

directory; will be written as FONT_UNIMAP to _/etc/vconsole.conf_ in the
initramfs
**locale.LANG=**_<locale>_::
taken from the environment; if no UNICODE is defined we set its value in
basis of LANG value (whether it ends with ".utf8" (or similar) or not); will
be written as LANG to _/etc/locale.conf_ in the initramfs; e.g.:
+
----
locale.LANG=pl_PL.utf8
----
**locale.LC_ALL=**_<locale>_::
taken from the environment; will be written as LC_ALL to _/etc/locale.conf_
in the initramfs
LVM
~~~
**rd.lvm=0**::
disable LVM detection
**rd.lvm.vg=**_<volume group name>_::
only activate the volume groups with the given name. rd.lvm.vg can be
specified multiple times on the kernel command line.
**rd.lvm.lv=**_<logical volume name>_::
only activate the logical volumes with the given name. rd.lvm.lv can be
specified multiple times on the kernel command line.
**rd.lvm.conf=0**::
remove any _/etc/lvm/lvm.conf_, which may exist in the initramfs
crypto LUKS
~~~~~~~~~~~
**rd.luks=0**::
disable crypto LUKS detection
**rd.luks.uuid=**_<luks uuid>_::
only activate the LUKS partitions with the given UUID. Any "luks-" of the
LUKS UUID is removed before comparing to _<luks uuid>_.
The comparisons also matches, if _<luks uuid>_ is only the beginning of the
LUKS UUID, so you don't have to specify the full UUID.
This parameter can be specified multiple times.
**rd.luks.allow-discards=**_<luks uuid>_::
Allow using of discards (TRIM) requests for LUKS partitions with the given UUID.
Any "luks-" of the LUKS UUID is removed before comparing to _<luks uuid>_.
The comparisons also matches, if _<luks uuid>_ is only the beginning of the
LUKS UUID, so you don't have to specify the full UUID.
This parameter can be specified multiple times.
**rd.luks.allow-discards**::
Allow using of discards (TRIM) requests on all LUKS partitions.
**rd.luks.crypttab=0**::
do not check, if LUKS partition is in _/etc/crypttab_
crypto LUKS - key on removable device support
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
**rd.luks.key=**_<keypath>:<keydev>:<luksdev>_::
_keypath_ is a path to key file to look for. It's REQUIRED. When _keypath_ ends with '.gpg' it's considered to be key encrypted symmetrically with GPG. You will be prompted for password on boot. GPG support comes with 'crypt-gpg' module which needs to be added explicitly.
+
_keydev_ is a device on which key file resides. It might be kernel name of devices (should start with "/dev/"), UUID (prefixed with "UUID=") or label (prefix with "LABEL="). You don't have to specify full UUID. Just its beginning will suffice, even if its ambiguous. All matching devices will be probed. This parameter is recommended, but not required. If not present, all block devices will be probed, which may significantly increase boot time.
+
If _luksdev_ is given, the specified key will only be applied for that LUKS device. Possible values are the same as for _keydev_. Unless you have several LUKS devices, you don't have to specify this parameter. The simplest usage is:
+
----
rd.luks.key=/foo/bar.key
----
+
As you see, you can skip colons in such a case.
+
[NOTE]
===============================
dracut pipes key to cryptsetup with _-d -_ argument, therefore you need to pipe
to crypsetup luksFormat with _-d -_, too!
Here follows example for key encrypted with GPG:
----
gpg --quiet --decrypt rootkey.gpg \
| cryptsetup -d - -v \
--cipher serpent-cbc-essiv:sha256 \
--key-size 256 luksFormat /dev/sda3
----
If you use plain keys, just add path to _-d_ option:
----
cryptsetup -d rootkey.key -v \
--cipher serpent-cbc-essiv:sha256 \
--key-size 256 luksFormat /dev/sda3
----
===============================

+
[IMPORTANT]
Do **not** use the default kernel naming scheme for the interface name,
as it can conflict with the kernel names. So, don't use "eth[0-9]+" for the
interface name. Better name it "bootnet" or "bluesocket".

Setup bridge <bridgename> with <ethnames>. <ethnames> is a comma-separated
list of physical (ethernet) interfaces. Bridge without parameters assumes bridge=br0:eth0
NFS
~~~
**root=**[_<server-ip>_:]_<root-dir>_[:_<nfs-options>_]::
mount nfs share from <server-ip>:/<root-dir>, if no server-ip is given, use
dhcp next_server. if server-ip is an IPv6 address it has to be put in
brackets, e.g. [2001:DB8::1]. NFS options can be appended with the prefix
":" or "," and are seperated by ",".

Set the NFSv4 domain name. Will overwrite the settings in _/etc/idmap.conf_.
CIFS
~~~
**root=**cifs://[_<username>_[:_<password>_]@]_<server-ip>_:_<root-dir>_::
mount cifs share from <server-ip>:/<root-dir>, if no server-ip is given, use
dhcp next_server. if server-ip is an IPv6 address it has to be put in
brackets, e.g. [2001:DB8::1]. If a username or password are not specified
as part of the root, then they must be passed on the command line through
cifsuser/cifspass.
+
[WARNING]
====
Passwords specified on the kernel command line are visible for all users via the file _/proc/cmdline_ and via dmesg or can be sniffed on the network, when using DHCP with DHCP root-path.

protocol defaults to "6", LUN defaults to "0". If the "servername" field is
provided by BOOTP or DHCP, then that field is used in conjunction with other
associated fields to contact the boot server in the Boot stage. However, if
the "servername" field is not provided, then the "targetname" field is then
used in the Discovery Service stage in conjunction with other associated

dracut.conf - configuration file(s) for dracut
SYNOPSIS
--------
_/etc/dracut.conf_ _/etc/dracut.conf.d/*.conf_ _/usr/lib/dracut/dracut.conf.d/*.conf_
Description
-----------
_dracut.conf_ is loaded during the initialisation phase of dracut. Command line
parameter will overwrite any values set here.
_*.conf_ files are read from /usr/lib/dracut/dracut.conf.d and /etc/dracut.conf.d.
Files with the same name in /etc/dracut.conf.d will replace files in /usr/lib/dracut/dracut.conf.d.
The files are then read in alphanumerical order and will overwrite parameters set in
_/etc/dracut.conf_. Each line specifies an attribute and a value. A '#'
indicates the beginning of a comment; following characters, up to the end of the
line are not interpreted.
dracut command line options will overwrite any values set here.
Configuration files must have the extension .conf; other extensions are ignored.
*dracutmodules+=*" __<dracut modules>__ "::

%description
dracut contains tools to create a bootable initramfs for 2.6 Linux kernels.
Unlike existing implementations, dracut does hard-code as little as possible
into the initramfs. dracut contains various modules which are driven by the
event-based udev. Having root on MD, DM, LVM2, LUKS is supported as well as
NFS, iSCSI, NBD, FCoE with the dracut-network package.
dracut is a new, event-driven initramfs infrastructure based around udev.

MKINITRD(8)
=========
:doctype: manpage
:man source: dracut
:man manual: dracut
NAME
----
mkinitrd - is a compat wrapper, which calls dracut to generate an initramfs
SYNOPSIS
--------
*mkinitrd* ['OPTION...'] [<initrd-image>] <kernel-version>
DESCRIPTION
-----------
mkinitrd creates an initramfs image <initrd-image> for the kernel with
version <kernel-version> by calling "dracut".
[IMPORTANT]
If a more fine grained control over the resulting image is needed,
"dracut" should be called directly.
OPTIONS
-------
**--version**::
print info about the version
**-v, --verbose**::
increase verbosity level
**-f, --force**::
overwrite existing initramfs file.
**--image-version*::
append the kernel version to the target image
<initrd-image>-<kernel-version>.
**--with=<module>**::
add the kernel module <module> to the initramfs.
**--preload=<module>**::
preload the kernel module <module> in the initramfs before any other kernel
modules are loaded. This can be used to ensure a certain device naming, which
should in theory be avoided and the use of symbolic links in /dev is
encouraged.
**--nocompress**::
do not compress the resulting image.
**--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]

This adds the following parameters:
rd.caps=1
turn the caps module on/off
rd.caps.initdrop=cap_sys_module,cap_sys_rawio
drop the specified comma separated capabilities
rd.caps.disablemodules=1
turn off module loading
rd.caps.disablekexec=1
turn off the kexec functionality
If module loading is turned off, all modules have to be loaded in the
initramfs, which are used later on. This can be done with
"rd.driver.pre="
rd.driver.pre=autofs4,sunrpc,ipt_REJECT,nf_conntrack_ipv4,....
Because the kernel command line would get huge with all those drivers, I
recommend to make use of $initramfs/etc/cmdline.
So, all rd.caps.* and rd.driver.pre arguments are in caps.conf can be
copied to $initramfs/etc/cmdline with "-i caps.conf /etc/cmdline".
Also all modules have to be loaded in the initramfs via "--add-drivers".
The resulting initramfs creation would look like this:
--add-drivers "autofs4 sunrpc ipt_REJECT nf_conntrack_ipv4 \
nf_defrag_ipv4 iptable_filter ip_tables
ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack

0. Introduction
i18n module provides internationalization for initramfs at runtime. It
is intended to be generic across different GNU/Linux distributions.
i18n and keyboard settings are stored in different files among
distributions. To deal with it avoiding hardcoding those differences in
the installation script we handle it by mappings between variables used
by dracut and the ones in the system. Package maintainer is expected to
create those for his/her distribution and it's appreciated to share it
with us, so we can include it in source package.
1. Hostonly vs Generic
If you invoke dracut with '-H' option, i18n module install script will
gather variables values from your configuration files using mappings
provided in "/etc/dracut.conf.d/<foo>.conf". Those variables will be
put in "etc/vconsole.conf" and "etc/locale.conf" files inside initramfs
image. Next it will install only declared font, keymaps and so.
When building generic image (dracut without '-H' option), install script
copies all content of directories: consolefonts, consoletrans, unimaps
and keymaps to image. Take into account that's about 4 MiB.
2. Configuration
2.1. Variables
The following variables are used by i18n install script and at initramfs
runtime:
KEYMAP - keyboard translation table loaded by loadkeys
KEYTABLE - base name for keyboard translation table; if UNICODE is
true, Unicode version will be loaded. Overrides KEYMAP.
EXT_KEYMAPS - list of extra keymaps to bo loaded (sep. by space)
UNICODE - boolean, indicating UTF-8 mode
FONT - console font
FONT_MAP - see description of '-m' parameter in setfont manual
FONT_UNIMAP - see description of '-u' parameter in setfont manual
The following are appended to EXT_KEYMAPS only during build time:
UNIKEYMAP
GRP_TOGGLE
They were used in 10redhat-i18n module, but not sure of its purpose.
I'm leaving it in case... The following are taken from the environment:
LANG
LC_ALL
If UNICODE variable is not provided, script indicates if UTF-8 should be
used on the basis of LANG value (if it ends with ".utf8" or similar).
2.2. Setting up mappings
Mappings between variables listed in 2.1. and the ones spread around
your system are set up in /etc/dracut.conf.d/<foo>.conf. You need to
assign mappings to i18n_vars. Here's an example:
i18n_vars="/etc/conf.d/keymaps:KEYMAP,EXTENDED_KEYMAPS-EXT_KEYMAPS /etc/conf.d/consolefont:CONSOLEFONT-FONT,CONSOLETRANSLATION-FONT_MAP /etc/rc.conf:UNICODE"
First we've got name of file in host file system tree. After colon
there's mapping: <from>-<to>. If both variables have the same name you
can enter just a single, but it's important to specify it! The module
will source only variables you've listed.
Below there's detailed description in BNF:
<list> ::= <element> | <element> " " <list>
<element> ::= <conf-file-name> ":" <map-list>
<map-list> ::= <mapping> | <mapping> "," <map-list>
<mapping> ::= <src-var> "-" <dst-var> | <src-var>
We assume no whitespace are allowed between symbols.
<conf-file-name> is a file holding <src-var> in your system.
<src-var> is a variable holding value of meaning the same as <dst-var>.
<dst-var> is a variable which will be set up inside initramfs.
If <dst-var> has the same name as <src-var> we can omit <dst-var>.
Example:
/etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS
<list> = /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS
<element> = /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS
<conf-file-name> = /etc/conf.d/keymaps
<map-list> = KEYMAP,extended_keymaps-EXT_KEYMAPS
<mapping> = KEYMAP
<src-var> = KEYMAP
<mapping> = extended_keymaps-EXT_KEYMAPS
<src-var> = extended_keymaps
<dst-var> = EXT_KEYMAPS
2.3. Additional settings
If you encounter following error message: "Directories consolefonts,
consoletrans, keymaps, unimaps not found.", you can provide path where
those directories lie in your system by setting kbddir in configuration
file (the same where you put mappings).
3. Kernel parameters
If you create generic initramfs you can set up i18n by kernel
parameters using variables listed in 2.1. (except of UNIKEYMAP
and GRP_TOGGLE) The recommended minimum is: FONT and KEYMAP.
