01fips: trim off GRUB boot device from BOOT_IMAGE

E.g. in RHCOS, the `BOOT_IMAGE` from the cmdline is:

(hd0,gpt1)/ostree/rhcos-e493371e5ee8407889029ec979955a2b86fd7e3cae5a0591b9db1cd248d966e8/vmlinuz-4.18.0-146.el8.x86_64

Which of course is a GRUB thing, not an actual pathname we'll be able to
resolve. In fact, we can simply scrap it off from the variable. Our code
is already able to handle both cases: whether the device refers to a
separate boot partition, or just the root filesystem with a regular
`/boot` directory.

+## @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/initrd 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.
+
+Initramfs images are also called "initrd".
+
+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 saved 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.
+
+USAGE

+= 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
+  $prefix/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.

+_/usr/lib/dracut/dracut.conf.d/*.conf_
+
+Description
+-----------
+_dracut.conf_ is loaded during the initialisation phase of dracut. Command line
+parameter will override 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 override 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 override any values set here.
+
+Configuration files must have the extension .conf; other extensions are ignored.
+
+*add_dracutmodules+=*" __<dracut modules>__ "::

+    Specify a space-separated list of dracut modules to call when building the
+    initramfs. Modules are located in _/usr/lib/dracut/modules.d_.
+    This option forces dracut to only include the specified dracut modules.
+    In most cases the "add_dracutmodules" option is what you want to use.
+
+*omit_dracutmodules+=*" __<dracut modules>__ "::
+    Omit a space-separated list of dracut modules to call when building the
+    initramfs. Modules are located in _/usr/lib/dracut/modules.d_.

+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 itself. 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 _parse-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 $hostonly variable is set, then the module check() function
+should be in "hostonly" mode, which means, that the check() should only return
+0, if the module is really needed to boot this specific host.
+
+check() should return with:
+
+0:: Include the dracut module in the initramfs.
+
+1:: Do not include the dracut module. The requirements are not fulfilled
+(missing tools, etc.)
+
+255:: Only include the dracut module, if another module requires it or if
+explicitly specified in the config file or on the argument list.
+
+
+=== module-setup.sh: depends()
+
+The function depends() should echo all other dracut module names the module
+depends on.
+
+=== module-setup.sh: cmdline()
+
+This function should print the kernel command line options needed to boot the
+current machine setup. It should start with a space and should not print a
+newline.
+
+=== module-setup.sh: install()
+
+The install() function is called to install everything non-kernel related.
+To install binaries, scripts, and other files, you can use the functions
+mentioned in <<creation>>.
+
+To address a file in the current module directory, use the variable "$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 with more than two arguments is treated the same as
+inst_multiple, all arguments are treated as files to install and none as
+install destinations.
+
+==== 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>

 %description
-dracut is a new, event-driven initramfs infrastructure based around udev.
+dracut contains tools to create bootable initramfses for the Linux
+kernel. Unlike previous implementations, dracut hard-codes 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.usage.asc

@@ -0,0 +1,518 @@
+To create a initramfs image, the most simple command is:
+----
+# dracut
+----
+
+This will generate a general purpose initramfs image, with all possible
+functionality resulting of the combination of the installed dracut modules and
+system tools. The image is /boot/initramfs-_++<kernel version>++_.img and
+contains the kernel modules of the currently active kernel with version
+_++<kernel version>++_.
+
+If the initramfs image already exists, dracut will display an error message, and
+to overwrite the existing image, you have to use the --force option.
+----
+# dracut --force
+----
+
+If you want to specify another filename for the resulting image you would issue
+a command like:
+----
+# dracut foobar.img
+----
+
+To generate an image for a specific kernel version, the command would be:
+----
+# dracut foobar.img 2.6.40-1.rc5.f20
+----
+
+A shortcut to generate the image at the default location for a specific kernel
+version is:
+----
+# dracut --kver 2.6.40-1.rc5.f20
+----
+
+If you want to create lighter, smaller initramfs images, you may want to specify
+the --hostonly or -H option. Using this option, the resulting image will
+contain only those dracut modules, kernel modules and filesystems, which are
+needed to boot this specific machine. This has the drawback, that you can't put
+the disk on another controller or machine, and that you can't switch to another
+root filesystem, without recreating the initramfs image. The usage of the
+--hostonly option is only for experts and you will have to keep the broken
+pieces. At least keep a copy of a general purpose image (and corresponding
+kernel) as a fallback to rescue your system.
+
+=== Inspecting the Contents
+To see the contents of the image created by dracut, you can use the lsinitrd
+tool.
+----
+# lsinitrd | less
+----
+
+To display the contents of a file in the initramfs also use the lsinitrd tool:
+----
+# lsinitrd -f /etc/ld.so.conf
+include ld.so.conf.d/*.conf
+----
+
+=== Adding dracut Modules
+Some dracut modules are turned off by default and have to be activated manually.
+You can do this by adding the dracut modules to the configuration file
+_/etc/dracut.conf_ or _/etc/dracut.conf.d/myconf.conf_. See *dracut.conf*(5).
+You can also add dracut modules on the command line
+by using the -a or --add option:
+----
+# dracut --add bootchart initramfs-bootchart.img
+----
+
+To see a list of available dracut modules, use the --list-modules option:
+----
+# dracut --list-modules
+----
+
+=== Omitting dracut Modules
+Sometimes you don't want a dracut module to be included for reasons of speed,
+size or functionality. To do this, either specify the omit_dracutmodules
+variable in the _dracut.conf_ or _/etc/dracut.conf.d/myconf.conf_ configuration
+file (see *dracut.conf*(5)), or use the -o or --omit option
+on the command line:
+----
+# dracut -o "multipath lvm" no-multipath-lvm.img
+----
+
+=== Adding Kernel Modules
+If you need a special kernel module in the initramfs, which is not
+automatically picked up by dracut, you have the use the --add-drivers option
+on the command line or  the drivers vaiable in  the _/etc/dracut.conf_
+or _/etc/dracut.conf.d/myconf.conf_ configuration file (see *dracut.conf*(5)):
+----
+# dracut --add-drivers mymod initramfs-with-mymod.img
+----
+
+=== Boot parameters
+An initramfs generated without the "hostonly" mode, does not contain any system
+configuration files (except for some special exceptions), so the configuration
+has to be done on the kernel command line. With this flexibility, you can easily
+boot from a changed root partition, without the need to recompile the initramfs
+image. So, you could completly change your root partition (move it inside a md
+raid with encryption and LVM on top), as long as you specify the correct
+filesystem LABEL or UUID on the kernel command line for your root device, dracut
+will find it and boot from it.
+
+The kernel command line 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.
+
+If you specify ip=dhcp on the kernel command line, then dracut asks a dhcp
+server about the ip address 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 omitting 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:
+https://www.kernel.org/pub/linux/utils/boot/dracut/dracut.html
+
+
+[[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 from _/proc/cmdline_.
+* A copy of your disk partition information from _/etc/fstab_, which might be
+obtained booting an old working initramfs or a rescue medium.
+* Turn on dracut debugging (see _the 'debugging dracut' section_), and attach
+the file /run/initramfs/rdsosreport.txt.
+* If you use a dracut configuration file, please include _/etc/dracut.conf_ and
+all files in _/etc/dracut.conf.d/*.conf_
+
+[[network-root-device-related-problems]]
+==== Network root device related problems
+This section details information to include when experiencing problems on a
+system whose root device is located on a network attached volume (e.g. iSCSI,
+NFS or NBD). As well as the information from <<all-bug-reports>>, include the
+following information:
+
+
+* Please include the output of
++
+----
+# /sbin/ifup <interfacename>
+# ip addr show
+----
+
+[[debugging-dracut]]
+=== Debugging dracut
+
+
+[[configure-a-serial-console]]
+==== Configure a serial console
+
+Successfully debugging dracut will require some form of console
+logging during the system boot.  This section documents configuring a
+serial console connection to record boot messages.
+
+. First, enable serial console output for both the kernel and the bootloader.
+. Open the file _/boot/grub2/grub.cfg_ for editing. Below the line ''timeout=5'', add
+the following:
++
+----
+serial --unit=0 --speed=9600
+terminal --timeout=5 serial console
+----
++
+. Also in _/boot/grub2/grub.cfg_, add the following boot arguemnts to the ''kernel''
+line:
++
+----
+console=tty0 console=ttyS0,9600
+----
++
+. When finished, the _/boot/grub2/grub.cfg_ file should look similar to the example
+below.
++
+----
+default=0
+timeout=5
+serial --unit=0 --speed=9600
+terminal --timeout=5 serial console
+title Fedora (2.6.29.5-191.fc11.x86_64)
+  root (hd0,0)
+  kernel /vmlinuz-2.6.29.5-191.fc11.x86_64 ro root=/dev/mapper/vg_uc1-lv_root console=tty0 console=ttyS0,9600
+  initrd /dracut-2.6.29.5-191.fc11.x86_64.img
+----
++
+. More detailed information on how to configure the kernel for console output
+can be found at
+http://www.faqs.org/docs/Linux-HOWTO/Remote-Serial-Console-HOWTO.html#CONFIGURE-KERNEL.
+. Redirecting non-interactive output
++
+--
+NOTE: You can redirect all non-interactive output to _/dev/kmsg_ and the kernel
+will put it out on the console when it reaches the kernel buffer by doing
+
+----
+# exec >/dev/kmsg 2>&1 </dev/console
+----
+--
+
+[[using-the-dracut-shell]]
+==== Using the dracut shell
+
+dracut offers a shell for interactive debugging in the event dracut fails to
+locate your root filesystem. To enable the shell:
+
+. Add the boot parameter ''rd.shell'' to your bootloader configuration file
+(e.g. _/boot/grub2/grub.cfg_)
+. Remove the boot arguments ''rhgb'' and ''quiet''
++
+A sample _/boot/grub2/grub.cfg_ bootloader configuration file is listed below.
++
+----
+default=0
+timeout=5
+serial --unit=0 --speed=9600
+terminal --timeout=5 serial console
+title Fedora (2.6.29.5-191.fc11.x86_64)
+  root (hd0,0)
+  kernel /vmlinuz-2.6.29.5-191.fc11.x86_64 ro root=/dev/mapper/vg_uc1-lv_root console=tty0 rd.shell
+  initrd /dracut-2.6.29.5-191.fc11.x86_64.img
+----
++
+. If system boot fails, you will be dropped into a shell as seen in the example
+below.
++
+----
+No root device found
+Dropping to debug shell.
+
+#
+----
++
+. Use this shell prompt to gather the information requested above
+(see <<all-bug-reports>>).
+
+[[accessing-the-root-volume-from-the-dracut-shell]]
+==== Accessing the root volume from the dracut shell
+From the dracut debug shell, you can manually perform the task of locating and
+preparing your root volume for boot. The required steps will depend on how your
+root volume is configured. Common scenarios include:
+
+* A block device (e.g. _/dev/sda7_)
+* A LVM logical volume (e.g. _/dev/VolGroup00/LogVol00_)
+* An encrypted device
+  (e.g. _/dev/mapper/luks-4d5972ea-901c-4584-bd75-1da802417d83_)
+* A network attached device
+  (e.g. _netroot=iscsi:@192.168.0.4::3260::iqn.2009-02.org.example:for.all_)
+
+The exact method for locating and preparing will vary. However, to continue with
+a successful boot, the objective is to locate your root volume and create a
+symlink _/dev/root_ which points to the file system. For example, the following
+example demonstrates accessing and booting a root volume that is an encrypted
+LVM Logical volume.
+
+. Inspect your partitions using parted
++
+----
+# parted /dev/sda -s p
+Model: ATA HTS541060G9AT00 (scsi)
+Disk /dev/sda: 60.0GB
+Sector size (logical/physical): 512B/512B
+Partition Table: msdos
+Number  Start   End     Size    Type      File system  Flags
+1      32.3kB  10.8GB  107MB   primary   ext4         boot
+2      10.8GB  55.6GB  44.7GB  logical                lvm
+----
++
+. You recall that your root volume was a LVM logical volume. Scan and activate
+any logical volumes.
++
+----
+# lvm vgscan
+# lvm vgchange -ay
+----
++
+. You should see any logical volumes now using the command blkid:
++
+----
+# blkid
+/dev/sda1: UUID="3de247f3-5de4-4a44-afc5-1fe179750cf7" TYPE="ext4"
+/dev/sda2: UUID="Ek4dQw-cOtq-5MJu-OGRF-xz5k-O2l8-wdDj0I" TYPE="LVM2_member"
+/dev/mapper/linux-root: UUID="def0269e-424b-4752-acf3-1077bf96ad2c" TYPE="crypto_LUKS"
+/dev/mapper/linux-home: UUID="c69127c1-f153-4ea2-b58e-4cbfa9257c5e" TYPE="ext3"
+/dev/mapper/linux-swap: UUID="47b4d329-975c-4c08-b218-f9c9bf3635f1" TYPE="swap"
+----
++
+. From the output above, you recall that your root volume exists on an encrypted
+block device. Following the guidance disk encryption guidance from the
+Installation Guide, you unlock your encrypted root volume.
++
+----
+# UUID=$(cryptsetup luksUUID /dev/mapper/linux-root)
+# cryptsetup luksOpen /dev/mapper/linux-root luks-$UUID
+Enter passphrase for /dev/mapper/linux-root:
+Key slot 0 unlocked.
+----
++
+. Next, make a symbolic link to the unlocked root volume
++
+----
+# ln -s /dev/mapper/luks-$UUID /dev/root
+----
++
+. With the root volume available, you may continue booting the system by exiting
+the dracut shell
++
+----
+# exit
+----
+
+[[additional-dracut-boot-parameters]]
+==== Additional dracut boot parameters
+For more debugging options, see *dracut.cmdline*(7).
+
+
+[[debugging-dracut-on-shutdown]]
+==== Debugging dracut on shutdown
+
+To debug the shutdown sequence on systemd systems, you can _rd.break_
+on _pre-shutdown_ or _shutdown_.
+
+To do this from an already booted system:
+----
+# mkdir -p /run/initramfs/etc/cmdline.d
+# echo "rd.debug rd.break=pre-shutdown rd.break=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.

+*lsinitrd* ['OPTION...'] [<image> [<filename> [<filename> [...] ]]]
+
+*lsinitrd* ['OPTION...'] -k <kernel-version>
+
+DESCRIPTION
+-----------
+lsinitrd shows the contents of an initramfs image. if <image> is omitted, then
+lsinitrd uses the default image _/boot/<machine-id>/<kernel-version>/initrd_ or
+_/boot/initramfs-<kernel-version>.img_.
+
+OPTIONS
+-------
+**-h, --help**::
+    print a help message and exit.
+
+**-s, --size**::
+    sort the contents of the initramfs by size.
+
+**-f, --file** _<filename>_::
+    print the contents of <filename>.
+
+**-k, --kver** _<kernel version>_::
+    inspect the initramfs of <kernel version>.
+
+**-m, --mod**::
+    list dracut modules included of the initramfs image.
+
+**--unpack**::
+    unpack the initramfs to the current directory, instead of displaying the contents.
+    If optional filenames are given, will only unpack specified files, else the whole image will be unpacked.
+    Won't unpack anything from early cpio part.
+
+**--unpackearly**::
+    unpack the early microcode initramfs to the current directory, instead of displaying the contents.
+    Same as --unpack, but only unpack files from early cpio part.
+
+**-v, --verbose**::
+    unpack verbosely
+
+AVAILABILITY
+------------
+The lsinitrd command is part of the dracut package and is available from

+MKINITRD(8)
+===========
+:doctype: manpage
+:man source:   dracut
+:man manual:   dracut
+
+NAME
+----
+mkinitrd-suse - is a compat wrapper, which calls dracut to generate an initramfs
+
+SYNOPSIS
+--------
+*mkinitrd* ['OPTION...']
+
+DESCRIPTION
+-----------
+*mkinitrd* creates an initramfs image <initrd-image> for the kernel with
+version <kernel-version> by calling *dracut*.
+
+[IMPORTANT]
+This version of mkinitrd is provided for compatibility with older
+versions of mkinitrd. If a more fine grained control over the
+resulting image is needed, *dracut* should be called directly.
+
+OPTIONS
+-------
+**-R, --version**::
+    print info about the version
+
+**-k** _<kernel_list>_::
+    List of kernel images for which initrd files are created (relative
+    to _boot_dir_), Image name should begin with the following string,
+    defaults to _vmlinux_ on ppc/ppc64, _image_ on s390/s390x and _vmlinuz_
+    for everything else.
+
+**-i** _<initrd_list>_::
+    List of file names (relative to _boot_dir_) for the initrd; positions
+    have to match the _kernel_list_. Defaults to _initrd_.
+
+**-m** _<module_list>_::
+    Modules to include in initrd, defaults to _INITRD_MODULES_ variable
+    in */etc/sysconfig/kernel*.
+
+**-f** _<feature_list>_::
+    Features to be enabled for the initrd. In general mkinitrd
+    configures the initrd for the root device it is started from. With
+    this option additional feature can be enabled.
+
+**-b** _<bootdir>_::
+    Boot directory, defaults to */boot*, where the initrd is created.
+
+**-d** _<root_device>_::
+    Root device, defaults to the device from which the root_dir is
+    mounted; overwrites the rootdev environment variable if set
+
+**-s** _<size>_::
+    Add splash animation and bootscreen to initrd.
+
+**-D** _<interface>::
+    Run dhcp on the specified interface (for example "eth0").
+
+**-I** _<interface>::
+    Configure the specified interface statically.
+
+**-a** _<acpi_dsdt>::
+    Attach compiled ACPI DSDT (Differentiated System Description Table)
+    to initrd. This replaces the DSDT of the BIOS. Defaults to the
+    _ACPI_DSDT_ variable in */etc/sysconfig/kernel*.
+
+**-M** _<map>::
+    System.map file to use.
+
+**-B**::
+    Don’t run the *update-bootloader(8)* script after the initrd(s) have
+    been created. This is useful if you call mkinitrd(8) for anything
+    else than the running system.
+
+**-A**::
+    Create a so called "monster initrd" which includes all available
+    features and modules. This calls dracut with --no-hostonly and
+    --no-hostonly-cmdline parameters internally, instead of the default
+    --hostonly and --hostonly-cmdline.
+
+**-v, --verbose**::
+    increase verbosity level
+
+**-L**::
+    Disable logging to _/var/log/YaST2/mkinitrd.log_. This is useful for
+    testing if you don’t want to clutter the system log.
+
+**--help**::
+    print a help message and exit.

+=========

+
+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

+        drop the specified comma separated capabilities

+rd.caps.disablekexec=1

+"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 \
