+NAME

+dracut - low-level tool for generating an initramfs image
+
+SYNOPSIS
+--------
+*dracut* ['OPTION...'] [<image> [_<kernel version>_]]
+
+DESCRIPTION
+-----------
+dracut creates an initial image used by the kernel for preloading the block
+device modules (such as IDE, SCSI or RAID) which are needed to access the root
+filesystem, mounting the root filesystem and booting into the real system.
+
+At boot time, the kernel unpacks that archive into RAM disk, mounts and uses it
+as initial root file system. All finding of the root device happens in this
+early userspace.
+
+For a complete list of kernel command line options see *dracut.cmdline*(7)
+
+OPTIONS
+-------
+**-f, --force**::
+    overwrite existing initramfs file.
+
+**-m, --modules** _<list of 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
+    parameter can be specified multiple times.
++
+[NOTE]
+===============================
+If [LIST] has multiple arguments, then you have to put these in quotes. For
+example:

+----
+===============================
+
+**-d, --drivers** _<list of kernel modules>_::
+    specify a space-separated list of kernel modules to exclusively include
+    in the initramfs. The kernel modules have to be specified without the ".ko"
+    suffix. This parameter can be specified multiple times.
++
+[NOTE]
+===============================
+If [LIST] has multiple arguments, then you have to put these in quotes. For

+
+**--fscks** [LIST]::
+    add a space-separated list of fsck tools, in addition to _dracut.conf_'s
+    specification; the installation is opportunistic (non-existing tools are
+    ignored)
++
+[NOTE]
+===============================
+If [LIST] has multiple arguments, then you have to put these in quotes. For
+example:
+----

+**-l, --local**::
+    activates the local mode. dracut will use modules from the current working
+    directory instead of the system-wide installed modules in
+    _/usr/lib/dracut/modules.d_.
+    This is useful when running dracut from a git checkout.
+
+**-H, --hostonly**::
+    Host-Only mode: Install only what is needed for booting the local host
+    instead of a generic host and generate host-specific configuration.
++
+[WARNING]
+====
+If chrooted to another root other than the real root device, use "--fstab" and
+provide a valid _/etc/fstab_.
+====
+
+**--no-hostonly**::
+    Disable Host-Only mode
+
+**--fstab**::
+    Use _/etc/fstab_ instead of _/proc/self/mountinfo_.
+
+**--add-fstab** _<filename>_ ::
+    Add entries of _<filename>_ to the initramfs /etc/fstab.
+
+**--mount** "_<device>_ _<mountpoint>_ _<filesystem type>_ _<filesystem options>_"::
+    Mount _<device>_ on _<mountpoint>_ with _<filesystem type>_ and _<filesystem
+    options>_ in the initramfs
+
+**-i, --include** _<SOURCE>_ _<TARGET>_::
+    include the files in the SOURCE directory into the
+    TARGET directory in the final initramfs. If SOURCE is a file, it will be
+    installed to TARGET in the final initramfs. This parameter can be specified
+    multiple times.
+
+**-I, --install** _<file list>_::
+    install the space separated list of files into the initramfs.
++
+[NOTE]
+===============================
+If [LIST] has multiple arguments, then you have to put these in quotes. For
+example:
++
+----
+# dracut --install "/bin/foo /sbin/bar"  ...
+----
+===============================
+
+**--gzip**::
+    Compress the generated initramfs using gzip. This will be done by default,
+    unless another compression option or --no-compress is passed. Equivalent to
+    "--compress=gzip -9"
+
+**--bzip2**::
+    Compress the generated initramfs using bzip2.
++
+[WARNING]
+====
+Make sure your kernel has bzip2 decompression support compiled in, otherwise you
+will not be able to boot. Equivalent to "--compress=bzip2"
+====
+
+**--lzma**::
+    Compress the generated initramfs using lzma.
++
+[WARNING]
+====
+Make sure your kernel has lzma decompression support compiled in, otherwise you
+will not be able to boot. Equivalent to "--compress=lzma -9"
+====
+
+**--xz**::
+    Compress the generated initramfs using xz.
++
+[WARNING]
+====
+Make sure your kernel has xz decompression support compiled in, otherwise you
+will not be able to boot. Equivalent to "--compress=xz --check=crc32
+--lzma2=dict=1MiB"
+====
+
+**--compress** _<compressor>_::
+    Compress the generated initramfs using the passed compression program. If
+    you pass it just the name of a compression program, it will call that
+    program with known-working arguments. If you pass a quoted string with
+    arguments, it will be called with exactly those arguments. Depending on what
+    you pass, this may result in an initramfs that the kernel cannot decompress.
+
+**--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 initramfs temporary directory for debugging purposes.
+
+FILES
+-----
+_/var/log/dracut.log_::
+    logfile of initramfs image creation
+
+_/tmp/dracut.log_::
+    logfile of initramfs image creation, if _/var/log/dracut.log_ is not
+    writable
+
+_/etc/dracut.conf_::
+    see dracut.conf5
+
+_/etc/dracut.conf.d/*.conf_::

+
+Configuration in the initramfs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+_/etc/conf.d/_::
+    Any files found in _/etc/conf.d/_ will be sourced in the initramfs to
+    set initial values. Command line options will override these values
+    set in the configuration files.
+
+_/etc/cmdline_::
+    Can contain additional command line options.

+DRACUT.CMDLINE(7)
+=================
+:doctype: manpage
+:man source:   dracut
+:man manual:   dracut
+
+NAME
+----
+dracut.cmdline - dracut kernel command line options
+
+DESCRIPTION
+-----------
+The root device used by the kernel is specified in the boot configuration
+file on the kernel command line, as always.
+
+The traditional _root=/dev/sda1_ style device specification is allowed, but not
+encouraged. The root device should better be identified by LABEL or UUID. If a
+label is used, as in _root=LABEL=<label_of_root>_ the initramfs will search all
+available devices for a filesystem with the appropriate label, and mount that
+device as the root filesystem. _root=UUID=<uuidnumber>_ will mount the partition
+with that UUID as the root filesystem.
+
+In the following all kernel command line parameters, which are processed by
+dracut, are described.
+
+"rd.*" parameters mentioned without "=" are boolean parameters. They can be
+turned on/off by setting them to {0|1}. If the assignment with "=" is missing
+"=1" is implied. For example _rd.info_ can be turned off with _rd.info=0_ or
+turned on with _rd.info=1_ or _rd.info_. The last value in the kernel command
+line is the value, which is honored.
+
+Standard
+~~~~~~~~
+**init=**_<path to real init>_::
+    specify the path to the init programm to be started after the initramfs has
+    finished
+
+**root=**_<path to blockdevice>_::
+    specify the block device to use as the root filesystem.
++
+E.g.:
++
+----
+root=/dev/sda1
+root=/dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0-part1
+root=/dev/disk/by-label/Root
+root=LABEL=Root
+root=/dev/disk/by-uuid/3f5ad593-4546-4a94-a374-bcfb68aa11f7
+root=UUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7
+root=PARTUUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7
+----
+
+**rootfstype=**_<filesystem type>_:: "auto" if not specified, e.g.:
++
+----
+rootfstype=ext3
+----
+
+**rootflags=**_<mount options>_::
+    specify additional mount options for the root filesystem. If not set,
+    _/etc/fstab_ of the real root will be parsed for special mount options and
+    mounted accordingly.
+
+**rd.fstab=0**::
+    do not honor special mount options for the root filesystem found in
+    _/etc/fstab_ of the real root.
+
+**resume=**_<path to resume partition>_
++
+E.g.:
++
+----
+resume=/dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0-part1
+resume=/dev/disk/by-uuid/3f5ad593-4546-4a94-a374-bcfb68aa11f7
+resume=UUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7

+    LUKS UUID, so you don't have to specify the full UUID.
+    This parameter can be specified multiple times.
+
+**rd.luks.allow-discards::
+    Allow  using  of discards (TRIM) requests on all LUKS partitions.
+
+**rd.luks.crypttab=0**::
+    do not check, if LUKS partition is in _/etc/crypttab_
+
+crypto LUKS - key on removable device support
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+**rd.luks.key=**_<keypath>:<keydev>:<luksdev>_::
+    _keypath_ is a path to key file to look for. It's REQUIRED. When _keypath_ ends with '.gpg' it's considered to be key encrypted symmetrically with GPG. You will be prompted for password on boot. GPG support comes with 'crypt-gpg' module which needs to be added explicitly.
++
+_keydev_ is a device on which key file resides. It might be kernel name of devices (should start with "/dev/"), UUID (prefixed with "UUID=") or label (prefix with "LABEL="). You don't have to specify full UUID. Just its beginning will suffice, even if its ambiguous. All matching devices will be probed. This parameter is recommended, but not required. If not present, all block devices will be probed, which may significantly increase boot time.
++
+If _luksdev_ is given, the specified key will only be applied for that LUKS device. Possible values are the same as for _keydev_. Unless you have several LUKS devices, you don't have to specify this parameter. The simplest usage is:
++
+----
+rd.luks.key=/foo/bar.key
+----
++
+As you see, you can skip colons in such a case.
+

-    <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>

-      <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/lib/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>

-        <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>

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>

-        <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>

-      <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.

-      <title>dracut Components</title>
-      <para>dracut uses a modular system to build and extend the initramfs image. All modules are located in <filename>/usr/lib/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>
-        <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>

-        <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>
