--force-add [LIST] Force to add a space-separated list of dracut modules
to the default set of modules, when -H is specified.
-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.
--force-drivers [LIST] Specify a space-separated list of kernel
modules to add to the initramfs and make sure they
are tried to be loaded via modprobe same as passing
rd.driver.pre=DRIVER kernel parameter.
--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.
-k, --kmoddir [DIR] Specify the directory, where to look for kernel
modules
--fwdir [DIR] Specify additional directories, where to look for
firmwares, separated by :
--kernel-only Only install kernel drivers and firmware files
--no-kernel Do not install kernel drivers and firmware files
--print-cmdline Print the kernel command line for the given disk layout
--early-microcode Combine early microcode with ramdisk
--no-early-microcode Do not combine early microcode with ramdisk
--kernel-cmdline [PARAMETERS] Specify default kernel command line parameters
--strip Strip binaries in the initramfs
--nostrip Do not strip binaries in the initramfs
--prelink Prelink binaries in the initramfs
--noprelink Do not prelink binaries in the initramfs
--hardlink Hardlink files in the initramfs
--nohardlink Do not hardlink files in the initramfs
--prefix [DIR] Prefix initramfs files with [DIR]
--noprefix Do not prefix initramfs files
--mdadmconf Include local /etc/mdadm.conf
--nomdadmconf Do not include local /etc/mdadm.conf
--lvmconf Include local /etc/lvm/lvm.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.
--ro-mnt Mount / and /usr read-only by default.
-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
5 - debug info (here starts lots of output)
6 - trace info (and even more)
-v, --verbose Increase verbosity level
-q, --quiet Decrease verbosity level
-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.
-N, --no-hostonly Disables Host-Only mode
--hostonly-mode <mode>
Specify the hostonly mode to use. <mode> could be
one of "sloppy" or "strict". "sloppy" mode is used
by default.
In "sloppy" hostonly mode, extra drivers and modules
will be installed, so minor hardware change won't make
the image unbootable (eg. changed keyboard), and the
image is still portable among similar hosts.
With "strict" mode enabled, anything not necessary
for booting the local host in its current state will
not be included, and modules may do some extra job
to save more space. Minor change of hardware or
environment could make the image unbootable.
DO NOT use "strict" mode unless you know what you
are doing.
--hostonly-cmdline Store kernel command line arguments needed
in the initramfs
--no-hostonly-cmdline Do not store kernel command line arguments needed
in the initramfs
--no-hostonly-default-device
Do not generate implicit host devices like root,
swap, fstab, etc. Use "--mount" or "--add-device"
to explicitly add devices as needed.
--hostonly-i18n Install only needed keyboard and font files according
to the host configuration (default).
--no-hostonly-i18n Install all keyboard and font files available.
--persistent-policy [POLICY]
Use [POLICY] to address disks and partitions.
POLICY can be any directory name found in /dev/disk.
E.g. "by-uuid", "by-label"
--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
--add-device "[DEV]" Bring up [DEV] in 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.
--install-optional [LIST] Install the space separated list of files into the
initramfs, if they exist.
--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.
--lzo Compress the generated initramfs using lzop.
Make sure that your kernel has lzo support compiled
in, otherwise you will not be able to boot.
--lz4 Compress the generated initramfs using lz4.
Make sure that your kernel has lz4 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
--printsize Print out the module install size
--sshkey [SSHKEY] Add ssh key to initramfs (use with ssh-client module)
--logfile [FILE] Logfile to use (overrides configuration setting)
If [LIST] has multiple arguments, then you have to put these in quotes.
