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
- renamed dracut_install() to inst_multiple() for consistent naming
- 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
- do not include adjtime and localtime anymore
- fixed generation of zfcp.conf of CMS setups
- install vt102 terminfo
dracut_install() is still there for backwards compat
- do not strip files in FIPS mode
- fixed iBFT interface configuration
- fs-lib: install fsck and fsck.ext*
- shutdown: fixed killall_proc_mountpoint()

dracut-027
==========
- dracut now has bash-completion
- require bash version 4
- systemd module now requires systemd >= 199
- 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
- added rescue module
- host_fs_types is now a hashmap
- new dracut argument "--regenerate-all"
- new dracut argument "--noimageifnotneeded"
- new man page dracut.bootup
- install all host filesystem drivers
- 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
- no more "mknod" in the initramfs!!
- replaced all "tr" calls with "sed"
- speedup with lazy kernel module dependency resolving
- lots of speedup optimizations and last but not least
- dracut-install:
- new binary to significanlty speedup the installation process
- dracut-functions.sh makes use of it, if installed

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:

A lot of things are/should be marked with "FIXME" in the code.
Items are ordered in priority.
INITRAMFS TODO
- use info and warn prefix
- generate systemd unit dracut-initramfs-restore in /run/systemd dynamically
- put "root=" parsing hooks in separate hook dir
- call "root=" parsing hooks after getting new rootpath from dhcp
- put mount hook in main initqueue loop / careful about resume!
- the hard-coded list of udev rules that we care about is kind of lame.
- panic fallback
- bridging/bonding without "netroot=" https://bugzilla.redhat.com/show_bug.cgi?id=822750
- progress indication for fsck https://bugzilla.redhat.com/show_bug.cgi?id=827118
- domain, searchdomain https://bugzilla.redhat.com/show_bug.cgi?id=840778
- disable write-ifcfg https://bugzilla.redhat.com/show_bug.cgi?id=840784
- check for /var to be mounted in convertfs https://bugzilla.redhat.com/show_bug.cgi?id=848172
- probably fix "--include" https://bugzilla.redhat.com/show_bug.cgi?id=849338
GENERATOR TODO
- remove wait for swap devs, if no "resume=" is given on the kernel command line
- add presets (predefined set of modules)
- add interpreter/plugin-scripts to be sourced at the beginning or end (can use dracut-functions)
- add mechanism for module specific command line options
- pkg-config integration, to make it easy for other packages to use us.
- default module specification could use some work
- udev rule copying, as mentioned above, is a bit too hard-coded
- 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.

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.

======
Harald Hoyer <harald@redhat.com>
v3.0, October 2013
:language: bash
= Introduction
This section is a modified version of
http://en.wikipedia.org/wiki/Initrd which is licensed under the
Creative Commons Attribution/Share-Alike License.
== Definition
An _initial ramdisk_ is a temporary file system used in the boot process of the
Linux kernel. _initrd_ and _initramfs_ refer to slightly different schemes for
loading this file system into memory. Both are commonly used to make
preparations before the real root file system can be mounted.
== Rationale
Many Linux distributions ship a single, generic kernel image that is intended to
boot as wide a variety of hardware as possible. The device drivers for this
generic kernel image are included as loadable modules, as it is not possible to
statically compile them all into the one kernel without making it too large to
boot from computers with limited memory or from lower-capacity media like floppy
disks.
This then raises the problem of detecting and loading the modules necessary to
mount the root file system at boot time (or, for that matter, deducing where or
what the root file system is).
To further complicate matters, the root file system may be on a software RAID
volume, LVM, NFS (on diskless workstations), or on an encrypted partition. All
of these require special preparations to mount.
Another complication is kernel support for hibernation, which suspends the
computer to disk by dumping an image of the entire system to a swap partition or
a regular file, then powering off. On next boot, this image has to be made
accessible before it can be loaded back into memory.
To avoid having to hardcode handling for so many special cases into the kernel,
an initial boot stage with a temporary root file system
—now dubbed early user space— is used. This root file system would contain
user-space helpers that would do the hardware detection, module loading and
device discovery necessary to get the real root file system mounted.
== Implementation
An image of this initial root file system (along with the kernel image) must be
stored somewhere accessible by the Linux bootloader or the boot firmware of the
computer. This can be:
* The root file system itself
* A boot image on an optical disc
* A small ext2/ext3 or FAT-formatted partition on a local disk
(a _boot partition_)
* A TFTP server (on systems that can boot from Ethernet)
The bootloader will load the kernel and initial root file system image into
memory and then start the kernel, passing in the memory address of the image.
Depending on which algorithms were compiled statically into it, the kernel can
currently unpack initrd/initramfs images compressed with gzip, bzip2 and LZMA.
== Mount preparations
dracut can generate a customized initrams image which contains only whatever is
necessary to boot some particular computer, such as ATA, SCSI and filesystem
kernel modules (host-only mode).
dracut can also generate a more generic initramfs image (default mode).
dracut's initramfs starts only with the device name of the root file system (or
its UUID) and must discover everything else at boot time. A complex cascade of
tasks must be performed to get the root file system mounted:
* Any hardware drivers that the boot process depends on must be loaded. All
kernel modules for common storage devices are packed onto the initramfs and then
udev pulls in modules matching the computer's detected hardware.
* On systems which display a boot rd.splash screen, the video hardware must be
initialized and a user-space helper started to paint animations onto the display
in lockstep with the boot process.
* If the root file system is on NFS, dracut does then:
** Bring up the primary network interface.
** Invoke a DHCP client, with which it can obtain a DHCP lease.
** Extract the name of the NFS share and the address of the NFS server from the
lease.
** Mount the NFS share.
* If the root file system appears to be on a software RAID device, there is no
way of knowing which devices the RAID volume spans; the standard MD utilities
must be invoked to scan all available block devices with a raid signature and
bring the required ones online.
* If the root file system appears to be on a logical volume, the LVM utilities
must be invoked to scan for and activate the volume group containing it.
* If the root file system is on an encrypted block device:
** Invoke a helper script to prompt the user to type in a passphrase and/or
insert a hardware token (such as a smart card or a USB security dongle).
* Create a decryption target with the device mapper.
dracut uses udev, an event-driven hotplug agent, which invokes helper programs
as hardware devices, disk partitions and storage volumes matching certain rules
come online. This allows discovery to run in parallel, and to progressively
cascade into arbitrary nestings of LVM, RAID or encryption to get at the root
file system.
When the root file system finally becomes visible:
* Any maintenance tasks which cannot run on a mounted root file system
are done.
* The root file system is mounted read-only.
* Any processes which must continue running (such as the rd.splash screen helper
and its command FIFO) are hoisted into the newly-mounted root file system.
The final root file system cannot simply be mounted over /, since that would
make the scripts and tools on the initial root file system inaccessible for any
final cleanup tasks. On an initramfs, the initial root file system cannot be
rotated away. Instead, it is simply emptied and the final root file system
mounted over the top.
If the systemd module is used in the initramfs, the ordering of the services
started looks like <<dracutbootup7>>.
== Dracut on shutdown
On a systemd driven system, the dracut initramfs is also used for the shutdown
procedure.
The following steps are executed during a shutdown:
* systemd switches to the shutdown.target
* systemd starts
/lib/systemd/system/shutdown.target.wants/dracut-shutdown.service
* dracut-shutdown.service executes /usr/lib/dracut/dracut-initramfs-restore
which unpacks the initramfs to /run/initramfs
* systemd finishes shutdown.target
* systemd kills all processes
* systemd tries to unmount everything and mounts the remaining read-only
* systemd checks, if there is a /run/initramfs/shutdown executable
* if yes, it does a pivot_root to /run/initramfs and executes ./shutdown.
The old root is then mounted on /oldroot.
/usr/lib/dracut/modules.d/99shutdown/shutdown.sh is the shutdown executable.
* shutdown will try to umount every /oldroot mount and calls the various
shutdown hooks from the dracut modules
This ensures, that all devices are disassembled and unmounted cleanly.

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.

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

:man manual: dracut
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>

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.

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.
[NOTE]
===============================
On RHEL-7 the hostonly mode is the default mode. Generic "non-hostonly" images
are created, if the dracut-config-generic rpm is installed. The rescue kernel
entry in the bootloader menu is also a generic image.
===============================
=== 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/grub2/grub.cfg_
(or _/boot/efi/EFI/redhat/grub.cfg_ for EFI systems), if
grub2 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=dhcp" >> 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=dhcp 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. _/boot/grub2/grub.cfg_ (or _/boot/efi/EFI/redhat/grub.cfg_ for EFI systems))
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.
. In _/boot/grub2/grub.cfg_ (or _/boot/efi/EFI/redhat/grub.cfg_ for EFI systems),
add the following boot arguments to the ''linux16''
line:
+
----
console=tty0 console=ttyS0,9600
----
+
. 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.
[[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. _/boot/grub2/grub.cfg_ (or _/boot/efi/EFI/redhat/grub.cfg_ for EFI systems))
. Remove the boot arguments ''rhgb'' and ''quiet''
+
A sample _grub.cfg_ bootloader configuration file snippet is listed below.
+
----
menuentry 'Red Hat Enterprise Linux Server (3.10.0-308.el7.x86_64) 7.0 (Maipo)' […] {
[…]
linux16 /vmlinuz-3.10.0-308.el7.x86_64 ro root=/dev/mapper/vg_uc1-lv_root console=tty0 rd.shell
initrd16 /initramfs-3.10.0-308.el7.x86_64.img
[…]
}
----
+
. If system boot fails, you will be dropped into a shell as seen in the example
below.
+
----
No root device found

+
. 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 - 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

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.
