This also changes the command line switch to be --add-device and the

The --device command line is still supported but it should be considered

1) strstr " $discarduuids " did not remove the optional

2) The lookup seems backwards. $luksdev ($luks in the other code copy)

Before this commit, the only way to trigger allow-discards was to

Credits go to Alexander Tsoy <bugs+gentoo@puleglot.ru> who provided the
patch with following explanation:
I get messages "Skipping program $env{DM_SBIN_PATH}/..." when
generating initramfs. This happens because some udev rules contains
variables in path to command:
$ egrep -r 'IMPORT\{program\}=\"\$' /lib64/udev/rules.d/
/lib64/udev/rules.d/10-dm.rules:ENV{DM_COOKIE}=="?*", IMPORT{program}="$env{DM_SBIN_PATH}/dmsetup udevflags $env{DM_COOKIE}"
[...]

I: *** Including module: dm ***
I: Skipping program $env{DM_SBIN_PATH}/dmsetup using in udev rule 10-dm.rules as it cannot be found
If new modules are introduced, or modules get renamed, or modules change
from builtin to real modules, we want to include them in the host-only
image, just to be safe.
An exception is multipath devices, child and top layer device may have
same uuid. As dm devices maintain /dev/mapper/* as persistent names,
just do not doing converting for them.
No automatic assembly is done anymore by default. You will have to
specify exactly what devices to assemble
("rd.md.uuid=" "rd.luks.uuid" ...)
or use "rd.auto=1" or "rd.auto" on the kernel command line.
For big servers with thousands of disks we don't want to assemble
everything by default (error prone, slow).
"inst busybox" no longer seems to work when busybox is at
/sbin/busybox. Reproduced on Fedora 18 (dracut-023-39.git20120910).
Use type -P to find the full path to busybox to solve this problem.
For devices with filesystem, udev /dev/disk/by-uuid/* links are always
reliable. So improve the get_persistent_dev() by using by-uuid/* firstly,
and fallback to use by-id/*

ismounted handles both find-by-dev and find-by-mnt, but there's two issues:
1. for find-by-dev, it use readlink to get the canonical dev name, but
lvm is different with other devices, the canonical name for lvm devices
are symlinks like /dev/mapper/vg-lv00
2. for nfs mounting, just use [ -b $dev ] is not enough, it need being handled
seperately.

handles these cases well, so just use findmnt instead of implement all the

/run will get mounted at $NEWROOT/run after switch_root, but it's not
there yet. bind-mount it in place so updates for /run actually land in
/run.
(also: remove a redundant check for existing directories. mkdir -p
doesn't do anything if the directory already exists.)
When emergency_shell() happens, it does 'setsid --help' to figure out if
the setsid binary supports the '-c' flag (to set the controlling tty).
This output shows up in the logs (and on-screen if you're using
rd.debug), which keeps confusing people looking for other problems.
Using "case" instead of "strstr" lets us avoid this.
It looks like ip=ibft has been busted since

Currently anaconda provides rd.md=0 on kernel's command line as a boot
time optimization if root is not on md device. But this leads to kdump
failure. We copy the command line from first kernel and if dump target
is on md device, it fails as we never try to assemble md devices as
rd.md=0.
We have already set rd.md.uuid though in /etc/cmdlind.d/ dir providing
dracut the info about what md devices to assemble. So this patch overrides
rd.md settings if rd.md.uuid is provided.
This is a stop gap measure to get kdump working on software raid
devices. Harald seems to have bigger cleanup plans for rd.md. Once
that happens, this patch will not be needed and things should
automatically be fixed.

If users had switched to systemd-183+ but have not completed
the usrmove, then the variable ${systemdutildir} will likely
refer to /usr/lib/systemd NOT /lib/systemd and thus the
systemd-udevd daemon may not be found.
So let's try a little harder and add another hard coded path
and if we don't find it, then bail out hard.
While such paths should not be included internally, we cannot
guarantee that external scripts with shebangs will not do this.
Some older versions of plymouth also resulted in double /'s
in some paths, so best deal with this gracefully.
If we are doing lazy dep solving and happen to process a script with a
shebang on e.g. /bin/bash before we encounter the actual binary itself
we effectively ignore the fact that we've been asked to resolve the deps
and put the item in the 'seen' hashmap. Thus when we later really do try
and resolve deps, we short circuit and don't do anything.
Example test case:
$ cd
$ mkdir -p foo/bin
$ cp /bin/bash foo/bin
$ echo '#!/bin/bash' >foo/bin/script
$ dracut-install -D $HOME/foo -R $HOME/foo/bin/script $HOME/foo/bin/bash
otherwise sha512hmac will error out with:
sha512hmac -c /sysroot/boot/.vmlinuz-2.6.32-220.el6.x86_64.hmac
Error opening "/boot/vmlinuz-2.6.32-220.el6.x86_64": No such file or directory.
Kdump dracut hooks need to enter emergency shell, currently it directly call
"sh -i -l", with recent dracut this does not work anymore without proper ctty.
It will be convinient to seperate a standalone function _emergency_shell for
dracut modules to call.
This reverts commit b2d225a669.
When there's no /sys/dev/block/$2/slaves/*/dev/ exists, $_x will
be assigned with '/sys/dev/block/$2/slaves/*/dev/', this is invalid.
That commit will lead to some warn msg like:
cat: /sys/dev/block/8:16/slaves/*/dev: No such file or directory
cat: /sys/dev/block/8:32/slaves/*/dev: No such file or directory

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.
We do not want to install dracut-install to /usr/bin until all
interfaces are set to stone and the manpage is written. Until then the
tool is dracut internal.
First, we just install the kernel module and keep track, what we
installed. At the very end, call modprobe and modinfo for firmwares to
resolve all kernel module dependencies. This speeds up image creation,
because we can call modprobe and modinfo with many modules.
The patch, acfab373 - Handle upper case MAC addresses in ifname
option,takes care of only the MAC conversion to lower case in the
interface name. But the same has to be taken care for BOOTIF also.
This patch takes care of changing the BOOTIF to lower case.
Note that sed has been used in the patch instead of tr, as it is not
compulsion to install tr by dracut in the initramfs and may not be

"brd +" is not valid for ipv6. This causes the 'ip addr add' command to

Depending on how the dasd_mod module was loaded, our device could have
already been marked as online or offline. We need to make the sysecho

already been set.
Anaconda used arguments of the form:

for static IP configuration. So if we get a value for "ip" that's an IP
address, look for gateway= and netmask= and related args to fill in the
ip config vars.

In some cases (at least in mine) mount(8) is in /usr/bin/mount and
not in /bin/mount as dmsquash-live-root.sh expects. PATH is set to
/usr/bin:/usr/sbin:/sbin:/bin in that script anyway.
The legacy argument is DASD=, and the new arguments should be the same
as the arguments for populating dasd.conf. If multiple arguments are
passed we can stack them by inserting a ',' between them.
dracut allows passing --mount option which mounts the specified devices.
But it does not wait for these devices to show up and mounting will fail
if devices do not show up by the time "mount" was called.
I am writing some patches to support kdump on iscsi target and I noticed
that one of the initqueue script was not called as we found the root
device and broke out of main loop.
There are two possible enancements to this patch.
- Introduce a time limited wait (rd.timeout something along the lines of
rd.retry). That will allow kdump to try to dump to a backup target if
primary targets fails to come up.
- Wait for UUID= and LABEL= to show up too. Right now kdump converts
UUID= and LABEL= to respective devices and passes /dev/* to dracut
--mount option. So I am not introducing the wait for UUID= or LABEL=
in this patch.

Basically, s390 is the only place I've ever seen TERM=dumb, and it's too
dumb to handle '\r', so --progress-bar produces waaaaay too much output.
The normal progress meter only prints something once per second, so
that's reasonable on terminals where '\r' doesn't work.

Every time url-lib gets imported we end up making the list of handlers
longer with redundant entries. That's silly - we shouldn't add items
that already exist.
Note that this means you'll have to manipulate the handler list yourself
if you want to change the position/priority of existing handlers.
Sometimes some hook script will need to be before the cleanup hook scripts
For example dhclient killing, nfs cleanup, etc. must not happen before kdump
because it will use their fuctionalities.
So here introduce a new hook pre-pivot-cleanup, all cleanup scripts will go there.
that means pre-pivot hook is splited to two hooks pre-pivot and pre-pivot-cleanup

Qemu/KVM provides virtfs, a paravirtualised filesystem that is
implemented by running the Plan 9 folder sharing protocol over
virtio.
Make booting with root=virtfs:foobar use the virtfs filesystem
with mount tag 'foobar' as root filesystem, to allow booting
virtual machines off virtfs.
Note that this only handles 9p over virtio (i.e. virtfs), and
doesn't attempt to handle mounting 9p filesystems over TCP/IP,

Another solution could be searching in directories found at

Mounting, unmounting and then mounting a disk partition takes some
time.
On embedded systems such as OLPC XO where we disable fsck and fstab
reading, the root options are not going to change throughout the
mount_root() function, so remounting is time consuming and without
change.
Detect and optimize for this case so that the filesystem is only
mounted once.
According to its comment in dracut-lib.sh:
splitsep ":" "one:all:the:rest" one two

current field is the last field, so it just gets "all".
For NetworkManager to properly take over a NFS-root system, we need to
have the interface name(s) in /tmp/net.ifaces and save the dhclient
lease. This lets the ifcfg module do its magic.
save_netinfo should properly write out /tmp/net.ifaces when needed, and
copies the dhclient files into place.
This makes sure the network is active and ready to use during the
initqueue/online hook.
It also makes it so you can run setup_net repeatedly without causing
error messages.
also fixup the logic what and when to mount.

If symlink is yet alone in target directory, inst_symlink will fail to

"export -n" is a bash extension, not part of POSIX, and is hence

wait_for_loginit does set +x (to turn off debugging temporarily), but
sometimes it would return before turning it back on. Move the set +x

live.updates allows you to specify the URL for an "updates image" that
should be applied to the live runtime before switch_root.
The URL can be anything supported by url-lib (http, https, ftp, possibly
nfs) and the image can be anything supported by img-lib (xz/gzip
compressed cpio/tar, uncompressed cpio/tar, filesystem image, etc.)
For curl_fetch_url (http/https/ftp):
- use --progress-bar (the output is less messy)
- print the URL we're fetching so the user know's what's happening
For curl and nfs:
- don't echo the filename if it was provided by the user
The "online" hook runs whenever a network interface comes online (that
is, once it's actually up and configured).
The initqueue --env argument is used to set "$netif" to the name of the
newly-online network interface.
Add new functions: all_ifaces_up, get_netroot_ip, ip_is_local, ifdown,
setup_net, set_ifname, ibft_to_cmdline
Use them in netroot.sh and parse-ip-opts.sh.
There's also a couple little unrelated cleanups.
Since cp won't copy a directory over a symlink, any updates that were
supposed to go into e.g. /lib would get dropped if you had /updates/lib
as an actual directory, but the target system had /lib->/usr/lib.
As described in https://bugzilla.redhat.com/show_bug.cgi?id=541410#c2,
if you want NetworkManager to take over an interface that you're using
for NFS root (or other network root device), you need to:
a) set UUID=<uuid> in ifcfg-<iface>, and
b) save the lease file as /var/lib/dhclient-<uuid>-<iface>.lease
This patch should make write-ifcfg handle both these things.
first check for omit, then mark the kernel module as seen
when we temporarily omit_drivers, we don't want to mark them as seen.
example: nfs.ko module in kernel-modules, but the nfs module
should be able to load it later on.
In kernel_only mode, we don't want to write /etc/cmdline.d
Correctly return the check functions, so we have a valid return of
for_each_host_dev_fs().
mdraid and dmraid functions had wrong checkings for the filesystem
type.
Due to the way the main loop runs to detect partions, the same one
might be included twice (albeit via different symlinks.
This code simply prevents the same combo being activated twice.
A better fix might simply be to not include duplicate (after
resolving symlinks) entries in the host_fs_types variable.
If you do "fetch_url $url/.somefile", fetch_url would return failure,
because "$outdir/*" wouldn't match the file.
Use ls -A (which busybox ls supports) to actually find possible dotfiles

For kdump we need scp vmcore to remote machine, the nic to be used is
not limited to netroot one. we need a feature for manually bringing up

ssh-client for recovery or test purpose
I implement this by adding one argument to ifup script, user can use
`/sbin/ifup eth0 -m` to bring up eth0, note ifup will regard it a
manual operation for the nic specified in 1st argument if there's
the 2nd argument.
If same nic is used for netroot the 2nd argument will be ignored,
in this case we will leave netroot bring up it automatically to
avoid side effect. And in this case hooks such as kdump will need to
execute after netroot mounted.
`ifup eth0 -m` will create /tmp/net.eth0.manualup stamp file,
later dhclient-script can check this and pass $2 to netroot,
then netroot script will bring eth0 up

When booting with nfsroot, dracut doesn't necessarily set the initial
hostname correctly.
According to dhcp-options(5), the name may or may not be qualified with
the local domain. It goes on to say "it is preferable to use the
domain-name option to specify the domain name".
So dhclient-script needs to be able to handle the cases: a) where
host-name is fully qualified and domain name is also specified; b)
where hostname is fully qualified and the domain is not separately
specified; c) where host-name is "short" and domain-name is also
specified; and d) do its best where host-name is short but domain-name
is not specified.
The dhclient-script in initramfs does not handle case "c", apparently
the preferred situation properly, setting hostname to "short".

When the initqueue cannot be processed, it might be about an invalid
root device (in which case a separate message produced via
wait_for_dev() should be displayed anyway), but it could also
be for any other reason (e.g. /dev/resume not existing).
Therefore, it is best to use a more generic error message.
Also a minor tab->space conversion in the near vacinity of
the real change.
This commit allows the waiting for a device to be cancelled.
When the resume partition does not exist, it becomes quite hard
to work out what to do (you have to either create the
/dev/resume symlink manually, or remove the 'finished' job
that is waiting for it). Additionally dracut incorrectly
displays a message about not being able to find the root
device, which is bogus and misleading.
This commit should just bail on the whole resume thing
if the device cannot be found and proceed with a normal boot.
This should fix initial initrd generation during install.
If the modules are not desired to be used, the nokmsboot kernel
command line should disable them.

The kernel's primary console device is determined by the last "console="

1. Boot with a kernel command line ending in
console=tty0 console=ttyS0,115200
2. Observe both tty0 and ttyS0.
The output of init scripts is sent to ttyS0, as the final "console="

inst_script checks for a shebang, if it doesn't exist it exits.
If it does it should not be calling inst_binary, it should call
inst_simple like it used to.
The Xen module is unnecessary and it has been for a while.
Most Xen systems will not be using the module, even now, because
xen-detect is not installed by default on most Xen systems, and
dracut uses xen-detect to decide whether to include the module.
It also has some problems:
1) it does not try loading xen_platform_pci;
2) it loads modules unnecessarily; modules.alias is where all Xen support
should reside. Assuming xenbus_probe_frontend and xen_platform_pci
are loaded so that Xen devices are probed, other modules are picked up
automatically thanks to aliases such as
alias xen:vbd xen_blkfront
3) Even not-so-recent kernels (say 2.6.32) require the xen_platform_pci
and xenbus_probe_frontend modules even for non-paravirtualized guests.
60xen/module-setup.sh picks the module only for PV guests.
So, just require xenbus_probe_frontend to be builtin, and also
xen_platform_pci for fully-virtualized guests, and remove the module.

Reworked the flow of the rules file a bit, removed redundant tests, also
should be easier to follow. It's much shorter now as well, a bit more
similar to 90lvm script - both revolve around same concepts after all.
There's no reason to treat conf-assembled arrays differently from
incremental ones. Once we hit timeout in init's udev loop, we can use
common script (mdraid_start.sh) to try force inactive arrays
into degraded mode.
md-finished.sh was kind-of out of place - it didn't really wait for any
particular device(s) to show up, just watched if onetime mdadm scripts
are still in place. Furthermore, after moving mdraid_start to --timeout
initqueue, it didn't really have too much to watch at all, besides
mdadm_auto (and that served no purpose, as we do wait for concrete
devices).
Either way, with stock 64-md fixes, current version of 65-md*.rules does
the following:
- limits assembly to certain uuids, if specified
- watch for no ddf/imsm
- if mdadm.conf => setup onetime -As script, without forced --run option
- if !mdadm.conf => incrementally assemble
- for both cases, setup timeout script, run-forcing arrays as a last resort
Signed-off-by: Michal Soltys <soltys@ziu.info>
1) mdadm -As --auto=yes --run 2>&1 | vinfo (removed)
Currently such auto assembly will not complete or force-run partially
assembled arrays. It might assemble "concurrent" separate array and
force-run it, if possible (though the chances of suddenly showing
missing components in this scenario - a script run after udev timeout -
are pretty thin). See [1] for details. Also see #3 below.
2) mdadm -Is --run 2>&1 (removed)
This will only force-run native arrays - arrays in containers will not
be affected. See [1] for details. Also see #3 below.
3) mdadm -R run loop (implicitly handles #1 & #2)
This loop does everywthing that #1 & #2 are expected to do. Thus, the
above invocations are simply redundant and this is the most safe and
flexible option.
Also, it shouldn't be necessary to go under md/ directory, as those are
just symlinks to /dev/md[0-9]*.
Certain checks were changed to strict ones (array state, degraded state)
instead of relying on env tricks.
'cat' was added explicitly to installed programs (it has been used
implicitly in shutdown script either way)
4) mdmon bug
See [1] for details as well. In short - force-run arrays in containers
will not have mdmon started, so we do that manually.
5) stop/run queue magic
Also removed. mdadm -R will only cause change events to the array
itself, and they should not be an issue.

Currently shipped mdadm rules incrementally assemble all imsm and native

- fine-grained controls in 65-md* are shadowed - for example,

- 90dmraid might also conflict with 90mdraid, if user prefers the former
to handle containers

[harald@redhat.com: fixed network kernel module filter]
The local variable _mpargs in function instmods() in file dracut-functions
looks peculiar. The documentation is non-existent, but still ...
First, $_mpargs is not passed to modprobe via for_each_kmod_dep.
This is strange because my guess is that "_mpargs" means
"extra arguments for modprobe".
Second, the leading "--" will be lopped when a leading pathname
is stripped via
_mod=${_mod##*/}
It seems to me that a leading "--" should inhibit modification.
Here's the corresponding patch to current HEAD (from dracut-013.)

If we're about to start a Live image (i.e. if /dev/mapper/live-rw
exists) this script will take any files found in /updates (inside the
initramfs!) and and copy them into $NEWROOT.
This allows for hotfixes to be applied to existing Live images without
rebuilding the entire image.

Currently dmsquash-live-root requires that squashfs images be named
"squashfs.img" and all others be "ext3fs.img" or "rootfs.img".
If we've got a live image in initramfs, this patch will make dracut use
losetup and det_fs to determine the actual filesystem type of the image.

fsck_single() operates directly on the device, so fstab is not
necessary. fs-lib functions make sure fscks don't complain.
Code is only commented out just in case I missed something.
To not pollute dracut-lib.sh, all the fsck related functions were moved
to fs-lib.sh. The functions available are as follows:
- fsck_single
this will detect/verify filesystem, check if it has necessary tools and
check the filesystem respecting additional flags (if any), using
specific "driver" (or falling back to generic one). Currently
available: fsck_drv_{com,xfs,std}. 'com' is used for tools following
typical subset of options/return codes (e.g. ext, jfs), 'std' is used
for "unknown" fs and doesn't assume it can be run non-interactively.
Please see comments around the code for more info.
- fsck_batch
this will check provided list of the devices;
Both of the above functions will fake empty fstab, to make generic fsck
not complain too much (excact devices are always provided on the command
line).
"Known" filesystems currently: ext234, reiser, jfs, xfs
- det_fs
Small bug fixed - as this function is meant to be called in $(), it may
not be verbose.
Current behaviour is:
- if detection is successful, use its result
- if detection is not successful, and filesystem is provided, return
the provided one; otherwise use auto
Previously, '-a' was added for ext[234] filesystems if other
conflicting flag were not present. It's being done automatically
in fsck_drv_com() now (also for jfs and reiser).
The livenet module allows you to use a root arg like:
root=live:http://server.name/path/to/live.img ip=dhcp
The named live image will be downloaded with wget and then set up as the
root device.
It currently supports FTP, HTTP, and HTTPS. dracut will try to install
the CA bundle (/etc/ssl/certs/ca-bundle.crt) into the initramfs so that
SSL certificate checking will work properly.
If an HTTPS URL is given and the site fails the certificate check, the
file will be rejected and the system will not boot into it.

if a value of a key on the kernel command line includes wildcards, these
would be expanded.
E.g., if you have "key=/dev/sd*" the value would be substituted with
"/dev/sda /dev/sda1 /dev/sda2" instead of returning "/dev/sd*"
The script that was generated always returned the status of the last test
condition, potentially missing any earlier non-existing devices.
The change assures, that the script returns 0 only if all expected
devices are found.

As Ray Strode explains, plymouth --has-active-vt may fail if the user
passes console=ttyS0 or something other not corresponding to
console=tty0, because plymouth is outputing to the serial console and
not a VT in this case.
In the initrd, the init script and the sbin/cryptroot-ask script use
flock with different lock files for the console: /.console_lock and
/.console.lock respectively
Use common fsck and det_fs code. Verify filesystem type more
aggressively, which has a chance to be more resistant to
accidental mistakes.
Also, there's no need to generate custom fstab for the sake of fsck
anymore.

Both functions will be used by rootfs-block and fstab-sys modules.
Both are based on code present in mount-root.sh, though few changes are

det_fs:
will try to determine filesystem type for supplied device, even if it's
not auto. If fs cannot be detected, or if the detected one differs from
the supplied one - a warning is issued (so user can fix its stuff later)
wrap_fsck:
will call fsck for specific device with optionally additional
fsckoptions. The function returns fsck return value.

If /proc/cmdline is empty (like if root=... is set in /etc/cmdline),
modules.d/99base/init will crash with a message saying "can't shift that
many" right before switch_root. The problem is in the block of code that
tries to look for init args. It does something like:
read CMDLINE </proc/cmdline
[...]
set $CMDLINE
shift
If CMDLINE="" then "set $CMDLINE" will dump all the variables to stdout.
(That should be "set -- $CMDLINE" instead.) Since there's no $1, the
"shift" causes an error, and dracut crashes.
The 'shift' was copy-and-pasted from the previous block. It doesn't
belong here; remove it.

- also support FIPS on separate LVM partition
- use small settle loop to get /boot
- "set -e" has no effect, if we use "||"
- make fips work with encrypted root and seperate boot
- moved to pre-pivot to support /boot in /
Given that we boot into a modern Linux distribution with the "/run" toplevel
directory, we can easily mount move the whole /run directory to the real
root in the end and have the complete initramfs later on in
/run/initramfs. All log files and /run states are still accessible and
to save space /run/initramfs can be removed later on.
Because the kernel does not mount a tmpfs on /run prior to unpacking the
initramfs cpio image, we have to copy ourselves very early to a tmpfs
and mount it on /run.
Due to lazy umount the old initramfs binaries should
be removed in the end by switch_root.
This feature can be turned on with "--prefix".
Fixes long-standing FIXME
Latest isomd5sum added an option to abort media check with ESC key,
but that key is taken by plymouth for switching to the detailed log
messages, making it impossible to abort checkisomd5.
Tested in text mode.
While on some systems (like Fedora) rpc_pipefs is mounted
automatically when sunrpc module is loaded, on Debian based systems it
needs to be mounted manually.
When '' was passed as outfile, dracut generated name with following
pattern:

With commit 486a1b9324 dracut skips ''

-v meaning has changed. Now it increases verbosity level. -q option has
been added, which decreases verbosity level. Both options might be
specified multiple times.
As mentioned in kernel/Documentation/xz.txt:
...
Notes on compression options
Since the XZ Embedded supports only streams with no integrity check
or CRC32, make sure that you don't use some other integrity check
type when encoding files that are supposed to be decoded by the
kernel. With liblzma, you need to use either LZMA_CHECK_NONE or
LZMA_CHECK_CRC32 when encoding. With the xz command line tool, use
--check=none or --check=crc32.
Using CRC32 is strongly recommended unless there is some other layer
which will verify the integrity of the uncompressed data anyway.
...
Moved dlog() to _do_dlog() and created dlog() which reads from stdin if
no arguments (except the loglevel) are given.
This enables e.g.:
dwarn "This is a warning!"
echo "This is a warning!" | dwarn
It's dash compatible to be used also at boot-time. For now it's included
by dracut-functions and replaces functions: dinfo(), dwarning() and
derror(). New options are introduced: -L|--stdlog, and -q|--quiet to
control stderr verbosity. Logging to file or syslog may be controlled by
options set in config file.
Note that code is not adjusted to the meaning of the new logging
functions, yet.
Doxygen formatted documentation (as a proposal, by the way) is included
in dracut-logger.
Every image gets handled the same way regardless of filesystem, so
let's use a filesystem-neutral name (rather than adding new
lines for every fstype anyone might want to use).
Otherwise there is no way to skip pasword prompt. --has-active-vt
seems to correctly catch also the case when plymouthd is started
but splash is disabled.

These parameters can now be specified multiple times:
-a|--add
--add-drivers
-m|--modules
-o|--omit
-d|--drivers
--filesystems
-I|--install
--fwdir
-i|--include
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 seperated 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

/boot/initramfs-caps.img
We want all "/var/run" information to live in /dev/.run, until the real
root is mounted.
Therefore we mount a tmpfs on /dev/.run, which can/will be bind/move mounted
on /var/run later on.
This allows creation of initramfs images which contain a Live system.
The primary use for this is keeping very large initramfs-based systems
(e.g. anaconda, the Fedora installer) compressed in-memory, by using a
compressed filesystem image like squashfs or btrfs.
dmsquash-live-genrules.sh will initqueue dmsquash-live-root itself
(rather than making udev rules) if the given live "device" is actually
an existing, plain file.
parse-dmsquash-live.sh will only accept paths that end in ".img".
dmsquash-live-root will only handle images named "*squashfs.img",
"*ext3fs.img", or "*btrfs.img".
btrfsctl is being replaced by the btrfs command in the upstream
tools, so change accordingly. Also, if we're using the btrfs module
we should probably make sure the btrfs driver gets installed.
inst_dir used the following to try to resolve a relative path:
[[ $target = ${target##*/} ]] && target="${file%/*}/$target"
inst_dir $target
This will only match if $target has no slashes, so something like
/usr/bin -> ../sbin would result in: inst_dir ../sbin, or
/usr/share -> local/share would result in: inst_dir local/share
which is not going to do the right thing.
Instead, we resolve any non-absolute link, like so:
[[ $target == ${target#/} ]] && target=$(dirname "$file")/$target
Thus /usr/bin -> ../sbin results in: inst_dir /usr/../sbin, and
/usr/share -> local/share results in: inst_dir /usr/local/share
which is what you would expect.
Some versions of dash don't behave as expected with code like this:
while IFS=: read a b c; do
blah
done
Thanks to Eric Mertens who identified the issue.
The FIPS installkernel() relies on the instmods() return value. So only
return 0, if the module and its dependencies were actually installed
correctly.

`modules.builtin.bin' is installed like a regular file, thereby ending
up in the wrong place when `--kmoddir' is in effect. Fix this by
specifying the installation destination.
New kernel argument syntax for LUKS-keydev is introduced:
rd.luks.key=<key_path>[:<key_dev>[:<luks_dev>]]
Unfolding <key_dev> in BNF:
<key_dev> ::= "UUID=" <uuid> | "LABEL=" <label> | <kname>
Where <kname> matches following regular expression:
^/dev/.*
<kname> need to be a character device and not a symlink for now.
For every rd.luks.key argument udev rule is created. That rule runs
test to check whether matching device contains <key_path>. If it does
it's applied to matching <luks_dev>.
New:
str_starts, str_replace
funiq - print new unique file name
mkuniqdir - create and print new unique dir
splitsep - splits given string 'str' with separator 'sep' into vars
udevmatch - create udev rule match for a device
Modified:
foreach_uuid_until - use $___ as a place holder

- use printf instead of echo because echo eats '\' as well

systemd-vconsole-setup was not designed to be run from udevd.
It checks locale environment to decide, whether UNICODE should
be enabled or disabled. Normally environment is setup by
systemd; but the only environment available in udev rules is
those from device properties. It means systemd-vconsole-setup
always assumes default C locale and disables UNICODE.
Revert to using built-in console_init which explicitly
imports locale settings from /etc/vconsole.conf. Alternative
is to revert 6545b9d7 and call console_init directly :)

On the OLPC XO-1, there is a noticable delay during boot while the
initramfs is loaded from disk and uncompressed, so we have an interest
in making it small. We are also pushed for disk space.
Using busybox instead of all the regular tools saves a lot of space.
I have not tried every module but the basics are working with busybox's
replacements. Our initramfs is now down to 1.9mb.

Let take a look at Linux sources, /usr/src/linux-2.6.35/init/main.c:
204: char * envp_init[MAX_INIT_ENVS+2] = { "HOME=/", "TERM=linux", NULL, };
857: run_init_process("/sbin/init");
817: static void run_init_process(char *init_filename)
818: {
819: argv_init[0] = init_filename;
820: kernel_execve(init_filename, argv_init, envp_init);
821: }
As we can see HOME=/ and TERM=linux are provided for init and this might be
expected on some systems (Gentoo comes to my mind, here ;-)). That's why we
should give to init the same set of env. vars as Linux kernel does.
A new dracut module to implement fstab.sys handling
This module implements fstab.sys handling. This has to happen after the root
mount and before the nfsroot-cleanup pre-pivot at least. I've made to happen at
the beginning of the pre-pivot scripts, although it should maybe be at the end
of the mount scripts. This latter would be harder to do because the actual
mount is currently done by 99mount-root.sh and there is no 2 digit integer
higher than 99 :-(
There are perhaps other ways of achieving this end, such as having the
nfsroot-cleanup trawl through the newroot's /etc/fstab and auto-magically
figure out if there are any mounts which are pre-requisites for the
/var/lib/nfs/rpc_pipefs mount and do them first. Likewise post pivot,
/etc/rc.sysinit could figure out of there are any pre-requisite mounts for
/var/lib/stateless/{writeable,state} before doing those mounts. In short, make
it the responsibility of anything doing a mount to check if there are any
pre-requisites in /etc/fstab and mount them first. However, this spreads the
changes needed over more places, so I favour the fstab.sys approach. Also, who
knows what other uses administartors may have put fstab.sys to? and this undoes
a regression caused by the move from mkinitrd to dracut.
I'm looking for a way to have a system with disposable storage that can be
rebooted and all filesystem changes are thrown away. After reboot, the system
starts with a fresh root volume again. The use case is for automated testing.
We run test scripts that could potentially not clean up after themselves.
This is almost like stateless, but the storage is local to the system (not
iSCSI, NFS or NBB).

First, it's duplicate code.
Second, it did not allow those who had plymouth installed to use other
methods, like the new usb key file. When building the initram,
it would install the plymouth cryptroot-ask script, and not
the crypt module one.
Added these new items to crypt module's cryptroot-ask.sh:
- 'unset' for used variables
- udevsettle
The non-plymouth cryptsetup prompt was using $1 instead of $device.
Changed prompt number from 1 to 5, as this is much nicer.
I believe plymouth already does infinite prompts.
Also added unset for usb key. Just saw it didn't unset its vars.
First we check if $libdir and $usrlibdir vars are already set in config
file. If not we perform simple detect. Vars are exported - to be useful
in module/check scripts.
Current kernels know how to uncompress bzip2 and xz, so use them for compressing
the initramfs if asked. The more compression the merrier.
Also add support for generating uncompressed images, although they
are usually not what you want.
This is a patch series I have been playing with for awhile.
It cleans up some of the dracut code and adds a PKGBUILD file to make
it easier to use in Arch Linux.
Kernel 2.6.35 (may be, earlier) split ahci into libahci.ko and ahci.ko
and added ahci_platform.ko. As a result, drivers ahci and ahci_platform
do not contain any symbol that are checked for storage modules (it is
libahci.ko that references ata_scsi_ioctl now). So add additional
symbol ahci_init_controller; it seems this is expected to be called by
every driver based on libahci.ko.

Note that there are still some patches queued upstream for fcoe-utils to
enable it to work with the new lldpad and to add support to fipvlan to
bring up FCoE connections without requiring fcoemon to run.
The invocations of the various tools as in this patch should be final though,
see the discussion in:
http://bugzilla.redhat.com/show_bug.cgi?id=563794
This is the second revision of this patch, which no longer adds /etc/fcoe
to the initrd as that is not needed.
lvchange and vgchange '--monitor n' will not prevent lvm from
attempting to dlopen the libdevmapper-event library.
dracut git commit 47ab3b6c5e introduced the use of '--monitor n' but
'--ignoremonitoring' is needed now that the libdevmapper-event library
isn't copied into the initramfs (ever since 0fae59d6eb)

On debian systems xen-detect does not resite somewhere in $PATH,
but under /usr/lib/xen-default/bin. This patch ensures that this
is searched as well when locating and installing xen-detect.
Common wisdom to enter single user on Linux is to edit command
line and add "single". This was not possible because switch_root
was always called with empty init arguments. Collect them from
command line and pass to real init when switching root.

Adds the readonly_overlay karg for cases where the dm snapshot should be set to readonly. Use case would be a livecd that is configured to have a readonly root where filling up the dm snapshot would cause a problem.
If multipath isn't installed, don't use it. If we're in hostonly mode,
only install the multipath module if it's used for / . Otherwise, if
the user was dumb enough to install it, they get it during bootup.
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.
.TP
\fBrootfallback=\fR\fI<path to blockdevice>\fR
specify the block device to use as the root filesystem, if the normal root cannot be found\&. This can only be a simple block device with a simple file system, for which the filesystem driver is either compiled in, or added manually to the initramfs\&. This parameter can be specified multiple times\&.
.TP

This parameter can be specified multiple times.
.TP
.BRrd_retry="<seconds>"
wait <seconds> until dracut tries to force assemble LVM or RAID volumes. If the root device is not found within <seconds>*2 then dracut fails and either drops to a shell, if rdshell is on the kernel command line, or exits with 1, which normally causes a kernel panic.

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
----

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.
