NAME

       dracut - create initial ramdisk images for preloading modules

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.

       For a complete list of kernel command line options see dracut.kernel(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/share/dracut/modules.d. This parameter can be specified
           multiple times.

       -o, --omit<list of dracut modules>
           omit a space-separated list of dracut modules. This parameter can
           be specified multiple times.

       -a, --add<list of dracut modules>
           add a space-separated list of dracut modules to the default set of
           modules. This parameter can be specified multiple times.

       --force-add<list of dracut modules>
           force to add a space-separated list of dracut modules to the
           default set of modules, when -H is specified. This parameter can be
           specified multiple times.

       -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.

       --add-drivers<list of kernel modules>
           specify a space-separated list of kernel modules to add to the
           initramfs. The kernel modules have to be specified without the
           ".ko" suffix. This parameter can be specified multiple times.

       --filesystems<list of filesystems>
           specify a space-separated list of kernel filesystem modules to
           exclusively include in the generic initramfs. This parameter can be
           specified multiple times.

       -k, --kmoddir<kernel directory>
           specify the directory, where to look for kernel modules

        --fwdir<dir>[:<dir>...]
           specify additional directories, where to look for firmwares. This
           parameter can be specified multiple times.

       --kernel-only
           only install kernel drivers and firmware files

       --no-kernel
           do not install kernel drivers and firmware files

       --mdadmconf
           include local /etc/mdadm.conf

       --nomdadmconf
           do not include local /etc/mdadm.conf

       --strip
           strip binaries in the initramfs (default)

       --nostrip
           do not strip binaries in the initramfs

       --prefix
           prefix initramfs files with /run/initramfs/

       --noprefix
           do not prefix initramfs files with /run/initramfs/ (default)

       -h, --help
           display help text and exit.

       --debug
           output debug information of the build process

       -v, --verbose
           increase verbosity level (default is info(4))

       -q, --quiet
           decrease verbosity level (default is info(4))

       -c, --conf<dracut configuration file>
           specify configuration file to use. Default: /etc/dracut.conf

       --confdir<configuration directory>
           specify configuration directory to use. Default: /etc/dracut.conf.d

       -l, --local
           activates the local mode. dracut will use modules from the current
           working directory instead of the system-wide installed modules in
           /usr/share/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.

               Warning
               If chrooted to another root other than the real root device,
               use "--fstab" and provide a valid /etc/fstab.

       --fstab
           Use /etc/fstab instead of /proc/self/mountinfo.

       -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.

       --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.conf(5)

       /etc/dracut.conf.d/*.conf
           see dracut.conf(5)

   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.
