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.

AVAILABILITY
