[LIST] Omit a space-separated list of dracut modules.
-a, --add
[LIST] Add a space-separated list of dracut modules.
-d, --drivers
[LIST] Specify a space-separated list of kernel modules to
exclusively include in the initramfs.
--add-drivers
[LIST] Specify a space-separated list of kernel
modules to add to the initramfs.
--omit-drivers
[LIST] Specify a space-separated list of kernel
modules not to add to the initramfs.
--filesystems
[LIST] Specify a space-separated list of kernel filesystem
modules to exclusively include in the generic
initramfs.

--strip Strip binaries in the initramfs
--nostrip Do not strip binaries in the initramfs (default)
--prefix [DIR] Prefix initramfs files with [DIR]
--noprefix Do not prefix initramfs files (default)
--mdadmconf Include local /etc/mdadm.conf
--nomdadmconf Do not include local /etc/mdadm.conf

--nolvmconf Do not include local /etc/lvm/lvm.conf
--fscks
[LIST] Add a space-separated list of fsck helpers.
--nofscks Inhibit installation of any fsck helpers.
-h, --help This message
--debug Output debug information of the build process
--profile Output profile information of the build process
-L, --stdlog [0-6] Specify logging level (to standard error)
0 - suppress any messages
1 - only fatal errors
2 - all errors
3 - warnings
4 - info (default)
5 - debug info (here starts lots of output)
6 - trace info (and even more)
-v, --verbose Increase verbosity level (default is info(4))
-q, --quiet Decrease verbosity level (default is info(4))
-c, --conf [FILE] Specify configuration file to use.
Default: /etc/dracut.conf
--confdir [DIR] Specify configuration directory to use *.conf files
from. Default: /etc/dracut.conf.d
--tmpdir [DIR] Temporary directory to be used instead of default
/var/tmp.
-l, --local Local mode. Use modules from the current working
directory instead of the system-wide installed in
/usr/lib/dracut/modules.d.
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.
--no-hostonly Disables Host-Only mode
--fstab Use /etc/fstab to determine the root device.
--add-fstab [FILE] Add file to the initramfs fstab
--mount "[DEV] [MP] [FSTYPE] [FSOPTS]"
Mount device [DEV] on mountpoint [MP] with filesystem
[FSTYPE] and options [FSOPTS] 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.
-I, --install
[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.
--bzip2 Compress the generated initramfs using bzip2.
Make sure your kernel has bzip2 decompression support
compiled in, otherwise you will not be able to boot.
--lzma Compress the generated initramfs using lzma.
Make sure your kernel has lzma support compiled in,
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
--sshkey [SSHKEY] Add ssh key to initramfs (use with ssh-client module)
If
[LIST] has multiple arguments, then you have to put these in quotes.
