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"

All kernel module related install commands moved from "install"
to "installkernel".
For "--kernel-only" all installkernel scripts of the specified
modules are used, regardless of any checks, so that all modules
which might be needed by any dracut generic image are in.
The basic idea is to create two images. One image with the kernel
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

Also, there is an attempt to keep things as distribution-agnostic as

something which is really interesting to have separate across them.

INITRAMFS TODO
- The hard-coded list of udev rules that we care about is kind of lame.
- automatic kexec fallback
- panic fallback
GENERATOR TODO
- Default module specification could use some work
- udev rule copying, as mentioned above, is a bit too hard-coded
- pkg-config integration, to make it easy for other packages to use us.
- add recovery image creator (mkrecovery)
CODE TODO
- document functions
- make function vars local, and prefix with "_"
Future Enhancement Requests
- run ssh server to enter crypto password or perform debugging (supported by debian)

otherwise you will not be able to boot.
--xz Compress the generated initramfs using xz.
Make sure that your kernel has xz support compiled
in, otherwise you will not be able to boot.
--compress [COMPRESSION] Compress the generated initramfs with the
passed compression program. Make sure your kernel
knows how to decompress the generated initramfs,
otherwise you will not be able to boot.
--no-compress Do not compress the generated initramfs. This will
override any other compression options.
--list-modules List all available dracut modules.
-M, --show-modules Print included module's name to standard output during
build.
--keep Keep the temporary initramfs for debugging purposes

## @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.

# Skip initialization if it's already done.

.TP
.BR \-l ", " \-\-local
local mode. Use modules from the current working
directory instead of the system-wide installed in
.IR /usr/share/dracut/modules.d .
Useful when running dracut from a git checkout.
.TP
.BR \-H ", " \-\-hostonly
Host-Only mode: Install only what is needed for
booting the local host instead of a generic host.
.TP
.BR \-i ", " \-\-include " \fISOURCE\fR" "" " \fITARGET\fR"
include the files in the SOURCE directory into the
target directory in the final initramfs.
.TP

install the space separated list of files into the initramfs.
.SH KERNEL COMMAND LINE
The root filesystem used by the kernel is specified in the boot configuration
file, as always. The traditional \fBroot=/dev/hda1\fR style device
specification is allowed. If a label is used, as in \fBroot=LABEL=rootPart\fR
the initrd will search all available devices for an ext2 or ext3 filesystem
with the appropriate label, and mount that device as the root filesystem.
\fBroot=UUID=uuidnumber\fR will mount the partition with that UUID as the
root filesystem.
.SH Standard

.TP
.B rd_plytheme=<theme name>
specify the plymouth bootsplash theme (fallback is text)
.SH LVM
.TP
.B rd_NO_LVM
disable LVM detection
.TP
.B rd_LVM_VG=<volume group name>
only activate the volume groups with the given name
.SH crypto LUKS
.TP
.B rd_NO_LUKS
disable crypto LUKS detection
.TP

.SH DMRAID
.TP
.B rd_NO_DM
disable DM RAID detection
.TP
.B rd_DM_UUID=<dmraid uuid>
only activate the raid sets with the given UUID
.SH DASD
.TP
.B dasd=....
same syntax as the kernel module parameter (s390 only)
.SH DHCP
.TP
.B root=dhcp
get IP from dhcp server, root-path option from dhcp specifies root location
.SH NFS
.TP
.B root=[<server-ip>:]<root-dir>[:<nfs-options>]
mount nfs share from <server-ip>:/<root-dir>, if no server-ip is given,
use dhcp next_server.
NFS options can be appended with the prefix "." or ","
.TP
.B root=nfs:[<server-ip>:]<root-dir>[:<nfs-options>]
.TP
.B root=nfs4:[<server-ip>:]<root-dir>[:<nfs-options>]
.TP
.B root=dhcp
root=dhcp alone directs initrd to look at the DHCP root-path where NFS
options can be specified.
root-path=<server-ip>:<root-dir>[,<nfs-options>]
root-path=nfs:<server-ip>:<root-dir>[,<nfs-options>]
root-path=nfs4:<server-ip>:<root-dir>[,<nfs-options>]
.TP
.B root=/dev/nfs nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]
\fBDeprecated!\fR kernel Documentation/filesystems/nfsroot.txt defines
this method.
This is supported by dracut but not recommended.
.SH iSCSI
.TP
.B root=iscsi:[username:password[reverse:password]@][<servername>]:[<protocol>]:[<port>]:[<LUN>]:<targetname>
protocol defaults to "6", LUN defaults to "0".
If the "servername" field is provided by BOOTP or DHCP, then that
field is used in conjunction with other associated fields to contact
the boot server in the Boot stage (Section 7). However, if the
"servername" field is not provided, then the "targetname" field is
then used in the Discovery Service stage in conjunction with other
associated fields.
http://tools.ietf.org/html/rfc4173
.TP
.B root=iscsi:[username:password[:reverse:password]@][<servername>]:[<protocol>]:[<port>]:[<LUN>]:<targetname>
e.g. root=iscsi:192.168.50.1::::iqn.2009-06.dracut:target0
.TP
.B root=??? netroot=iscsi:[username:password[:reverse:password]@][<servername>]:[<protocol>]:[<port>]:[<LUN>]:<targetname> ...
multiple netroot options allow setting up multiple iscsi disks
e.g.
root=UUID=12424547 netroot=iscsi:192.168.50.1::::iqn.2009-06.dracut:target0 netroot=iscsi:192.168.50.1::::iqn.2009-06.dracut:target1
.B not yet implemented
.TP
.B root=??? iscsi_initiator= iscsi_target_name= iscsi_target_ip= iscsi_target_port= iscsi_target_group= iscsi_username= iscsi_password= iscsi_in_username= iscsi_in_password=
.TP
.B root=??? iscsi_firmware
will read the iscsi parameter from the BIOS firmware
.SH NBD
.TP
.B root=nbd:<server>:<port>[:<fstype>][:<mountopts>]
mount nbd share from <server>
.TP
.B root=dhcp
with dhcp root-path=nbd:<server>:<port>[:<fstype>][:<mountopts>]
root=dhcp alone directs initrd to look at the DHCP root-path where NBD options can be specified.
This syntax is only usable in cases where you are directly mounting the volume as the rootfs.
.SH Network
.TP bootdev=<interface>
.B specify the network interface to boot from
.TP
.B ip={dhcp|on|any}
get ip from dhcp server from all interfaces. If root=dhcp, loop sequentially through all interfaces (eth0, eth1, ...) and use the first with a valid DHCP root-path.
.TP
.B ip=<interface>:{dhcp|on|any}
get ip from dhcp server on a specific interface
.TP
.B ip=<client-IP-number>:[<server-id>]:<gateway-IP-number>:<netmask>:<client-hostname>:<interface>:{none|off}
explicit network configuration
.SH Misc

.TP
.B rdbreak={cmdline|pre-udev|pre-trigger|initqueue|pre-mount|mount|pre-pivot}
drop to a shell on defined breakpoint
.TP
.B rdudevinfo
set udev to loglevel info
.TP
.B rdudevdebug
set udev to loglevel debug
.TP
.B rdnetdebug

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

<title>Introduction</title>
<section>
<title>Definition</title>
<para>An <emphasis>initial ramdisk</emphasis> is a temporary file system used in the boot process of the Linux kernel. <emphasis>initrd</emphasis> and <emphasis>initramfs</emphasis> 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.</para>
</section>
<section>
<title>Rationale </title>
<para>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.
</para>
<para>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).
</para>
<para>To further complicate matters, the root file system may be on a software <acronym>RAID</acronym> volume, <acronym>LVM</acronym>, <acronym>NFS</acronym> (on diskless workstations), or on an encrypted partition. All of these require special preparations to mount.
</para>
<para>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. </para>
<para>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.
</para>
</section>
<section>
<title>Implementation </title>
<para>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: </para>
<itemizedlist>
<listitem>
<para>The root file system itself </para>
</listitem>
<listitem>
<para>A boot image on an optical disc
</para>
</listitem>
<listitem>
<para>A small ext2/ext3 or <acronym>FAT</acronym>-formatted partition on a local disk (a <emphasis>boot partition</emphasis>)</para>
</listitem>
<listitem>
<para>A <acronym>TFTP</acronym> server (on systems that can boot from Ethernet) </para>
</listitem>
</itemizedlist>
<para>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.
</para>
<para>Depending on which algorithms were compiled statically into it, the kernel can currently unpack initrd/initramfs images compressed with gzip, bzip2 and <acronym>LZMA</acronym>. </para>
</section>
<section>
<title>Mount preparations </title>
<para>dracut can generate a customized initrams image which contains only whatever is necessary to boot some particular computer, such as <acronym>ATA</acronym>, <acronym>SCSI</acronym> and filesystem kernel modules (host-only mode).</para>
<para>dracut can also generate a more generic initramfs image (default mode). </para>
<para>dracut&apos;s initramfs starts only with the device name of the root file system (or its <acronym>UUID</acronym>) and must discover everything else at boot time. A complex cascade of tasks must be performed to get the root file system mounted: </para>
<itemizedlist>
<listitem>
<para>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&apos;s detected hardware. </para>
</listitem>
<listitem>
<para>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. </para>
</listitem>
<listitem>
<para>If the root file system is on NFS, dracut does then: <itemizedlist>
<listitem>
<para>Bring up the primary network interface. </para>
</listitem>
<listitem>
<para>Invoke a DHCP client, with which it can obtain a DHCP lease. </para>
</listitem>
<listitem>
<para>Extract the name of the NFS share and the address of the NFS server from the lease. </para>
</listitem>
<listitem>
<para>Mount the <acronym>NFS</acronym> share. </para>
</listitem>
</itemizedlist></para>
</listitem>
<listitem>
<para>If the root file system appears to be on a software <acronym>RAID</acronym> device, there is no way of knowing which devices the <acronym>RAID</acronym> volume spans; the standard <acronym>MD</acronym> utilities must be invoked to scan all available block devices with a raid signature and bring the required ones online. </para>
</listitem>
<listitem>
<para>If the root file system appears to be on a logical volume, the <acronym>LVM</acronym> utilities must be invoked to scan for and activate the volume group containing it. </para>
</listitem>
<listitem>
<para>If the root file system is on an encrypted block device: <itemizedlist>
<listitem>
<para>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 <acronym>USB</acronym> security dongle). </para>
</listitem>
<listitem>
<para>Create a decryption target with the device mapper. </para>
</listitem>
</itemizedlist></para>
</listitem>
</itemizedlist>
<para>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 <acronym>LVM</acronym>, <acronym>RAID</acronym> or encryption to get at the root file system. </para>
<para>When the root file system finally becomes visible: <itemizedlist>
<listitem>
<para>Any maintenance tasks which cannot run on a mounted root file system are done. </para>
</listitem>
<listitem>
<para>The root file system is mounted read-only. </para>
</listitem>
<listitem>
<para>Any processes which must continue running (such as the rd.splash screen helper and its command <acronym>FIFO</acronym>) are hoisted into the newly-mounted root file system. </para>
</listitem>
</itemizedlist></para>
<para>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.

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

<section>
<title>dracut Components</title>
<para>dracut uses a modular system to build and extend the initramfs image. All modules are located in <filename>/usr/share/dracut/modules.d</filename> or in <filename><replaceable>&lt;git-src&gt;</replaceable>/modules.d</filename>. The most basic dracut module is <filename>99base</filename>. In <filename>99base</filename> the initial shell script <command>init</command> is defined, which gets run by the kernel after initramfs loading. Although you can replace <command>init</command> with your own version of <filename>99base</filename>, 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 <xref linkend="stages"/>.</para>
<para>The main script, which creates the initramfs is <command>dracut</command> itsself. It parses all arguments and sets up the directory, in which everything is installed. It then executes all <command>check</command>, <command>install</command>, <command>installkernel</command> 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 <command>check</command>, <command>install</command> and <command>installkernel</command> are found in in the file <filename>dracut-functions</filename>. These shell functions are available to all module installer (<command>install</command>, <command>installkernel</command>) scripts, without the need to source <filename>dracut-functions</filename>.</para>
<para>A module can check the preconditions for <command>install</command> and <command>installkernel</command> with the <command>check</command> script. Also dependencies can be expressed with <command>check</command>. If a module passed <command>check</command>, <command>install</command> and <command>installkernel</command> 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 <command>installkernel</command>. All other files found in a module directory are module specific and mostly are hook scripts and udev rules.</para>
</section>
<section id="stages">
<title>Boot Process Stages</title>
<para>The <command>init</command> script in <filename>99base</filename> is the main script, which prepares the root file system for usage, runs udev, mounts the real root device, kills the remaining processes, and switches to the real root device for further booting. dracut modules can insert custom script at various points, to control the boot process. These hooks are plain directories containing shell scripts ending with &quot;.sh&quot;, which are sourced by <command>init</command>.
Common used functions are in <filename>dracut-lib.sh</filename>, which can be sourced by any script. </para>
<section>
<title>Basic Setup</title>
<para>The first thing <command>init</command> does, is to mount <filename>/proc</filename> and <filename>/sys</filename> and manually create the basic device nodes and symbolic links in <filename>/dev</filename> needed to execute basic commands. Then logging is setup according to kernel command line arguments. <filename>/dev/pts</filename> and <filename>/dev/shm</filename> are mounted and the first hook is sourced.</para>
</section>
<section>
<title>Hook: cmdline</title>
<para>The <literal>
<function>cmdline</function>
</literal> 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.</para>
<para>In this hook the most important environment variable is defined: <envar>root</envar>. The second one is <envar>rootok</envar>, which indicates, that a module claimed to be able to parse the <envar>root</envar> defined. So for example, <envar>root=</envar><replaceable>iscsi:....</replaceable> will be claimed by the <function>iscsi</function> dracut module, which then sets <envar>rootok</envar>.</para>
</section>
<section>
<title>Hook: pre-udev</title>
<para>This hook is executed right after the <function>cmdline</function> hook and a check if <envar>root</envar> and <envar>rootok</envar> were set. Here modules can take action with the final <envar>root</envar>, and before <command>udev</command> has been run.</para>
</section>
<section>
<title>Start Udev</title>
<para>Now <command>udev</command> is started and the logging for <command>udev</command> is setup.</para>
</section>
<section>
<title>Hook: pre-trigger</title>
<para>In this hook, you can set udev environment variables with <code>udevadm control --property=<envar>KEY</envar>=<replaceable>value</replaceable></code> or control the further execution of <command>udev</command> with <command>udevadm</command>.</para>
</section>
<section>
<title>Trigger Udev</title>
<para><command>udev</command> is triggered by calling <command>udevadm trigger</command>, which sends <constant>add</constant> events for all devices and subsystems.
</para>
</section>
<section>
<title>Main Loop</title>
<para>Now the main loop of <command>99base/init</command> begins. Here we loop until <command>udev</command> has settled and all scripts in <filename>initqueue-finished</filename> returned true. In this loop there are three hooks, where scripts can be inserted by calling <command>/sbin/initqueue</command>.
</para>
<section>
<title>Initqueue</title>
<para>This hook gets executed every time a script is inserted here, regardless of the <command>udev</command> state.</para>
</section>
<section>
<title>Initqueue settled</title>
<para>This hooks gets executed every time <command>udev</command> has settled.</para>
</section>
<section>
<title>Initqueue finished</title>
<para>This hook is called after <command>udev</command> has settled and if all scripts herein return <errorcode>0</errorcode> the main loop will be ended.</para>
</section>
</section>
<section>
<title>Hook: pre-mount</title>
<para>Before the root device is mounted all scripts in the hook pre-mount are executed. In some cases (e.g. <acronym>NFS</acronym>) the real root device is already mounted, though.</para>
</section>
<section>
<title>Hook: mount</title>
<para>This hook is mainly to mount the real root device.</para>
</section>
<section>
<title>Hook: pre-pivot</title>
<para>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.</para>
</section>
<section>
<title>Cleanup and switch_root</title>
<para>Init kills all <command>udev</command> processes, cleans up the environment, sets up the arguments for the real <command>init</command> process and finally calls <command>switch_root</command>. <command>switch_root</command> removes the whole filesystem hierarchy of the initramfs, chroot()s to the real root device and calls <command>/sbin/init</command> with the specified arguments.</para>
<para>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.</para>
</section>
</section>
<section>
<title>Network Infrastructure</title>
<para>
</para>
</section>
<section>
<title>Writing a Module</title>
<para>A simple example module is <filename>96insmodpost</filename>, which modprobes a kernel module after udev has settled and the basic device drivers have been loaded.</para>
<para>All module installation information is in the file module-setup.sh.</para>
<para>First we create a <function>check()</function> function, which just exits with <errorcode>0</errorcode> indicating that this module should be included by default.</para>
<para><function>check()</function>:</para>
<programlisting>return 0</programlisting>
<para>The we create the <function>install()</function> function, which installs a cmdline hook with priority number 20 called <filename>parse-insmodpost.sh</filename>. It also installs the <filename>insmodpost.sh</filename> script in <filename>/sbin</filename>.</para>
<para><function>install()</function>:</para>
<programlisting>inst_hook cmdline 20 &quot;$moddir/parse-insmodpost.sh&quot;
inst_simple &quot;$moddir/insmodpost.sh&quot; /sbin/insmodpost.sh</programlisting>
<para>The <filename>pase-instmodpost.sh</filename> parses the kernel command line for a argument <envar>rd.driver.post</envar>, blacklists the module from being autoloaded and installs the hook <filename>insmodpost.sh</filename> in the <filename>initqueue-settled</filename>.</para>
<para><filename>parse-insmodpost.sh</filename>:</para>
<programlisting>for p in $(getargs rd.driver.post=); do
echo &quot;blacklist $p&quot; &gt;&gt; /etc/modprobe.d/initramfsblacklist.conf
_do_insmodpost=1
done
[ -n &quot;$_do_insmodpost&quot; ] &amp;&amp; /sbin/initqueue --settled --unique --onetime /sbin/insmodpost.sh
unset _do_insmodpost
</programlisting>
<para><filename>insmodpost.sh</filename>, which is called in the <filename>initqueue-settled</filename> hook will just modprobe the kernel modules specified in all <envar>rd.driver.post</envar> kernel command line parameters. It runs after <command>udev</command> has settled and is only called once (<parameter>--onetime</parameter>).</para>
<para><filename>insmodpost.sh</filename>:</para>

modprobe $p

This adds the following parameters:

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 \

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
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.

Dracut gensplash module
-----------------------

0. Introduction
gensplash is based on Genkernel code and that's why it's Gentoo-specific. It
requires splashutils to work. To set up theme you may edit /etc/conf.d/splash
or set DRACUT_GENSPLASH_THEME and DRACUT_GENSPLASH_RES variables. Your theme
has to exist in /etc/splash and for every given resolution has to exist config
in theme's directory, e.g. there's 1024x768.cfg in /etc/splash/natural_gentoo.
List of resolutions is comma-separated.
NOTE: The module will be rewritten to be distro-neutral. Its name will change
to fbsplash.
1. Hostonly vs Generic
All available themes are installed only if no --hostonly is specified and no
DRACUT_GENSPLASH_THEME and DRACUT_GENSPLASH_RES are set. Otherwise those vars
are checked and if not set then config /etc/conf.d/splash is read.
2. Configuration and kernel parameters
Example set up by environment variables:
DRACUT_GENSPLASH_THEME=natural_gentoo
DRACUT_GENSPLASH_RES=1024x768,1024x600
Example kernel arguments:
splash=silent,theme:natural_gentoo console=tty1 quiet
You may easily set up the module using Genkernel with arguments:
--gensplash=<theme>:<res1>,<res2>,...
