[ []] Version: $DRACUT_VERSION Creates initial ramdisk images for preloading modules --kver [VERSION] Set kernel version to [VERSION]. -f, --force Overwrite existing initramfs file. [OUTPUT_FILE] --rebuild Append the current arguments to those with which the input initramfs image was built. This option helps in incrementally building the initramfs for testing. If optional [OUTPUT_FILE] is not provided, the input initramfs provided to rebuild will be used as output file. -a, --add [LIST] Add a space-separated list of dracut modules. --force-add [LIST] Force to add a space-separated list of dracut modules to the default set of modules, when -H is specified. -o, --omit [LIST] Omit a space-separated list of dracut modules. -m, --modules [LIST] Specify a space-separated list of dracut modules to call when building the initramfs. Modules are located in /usr/lib/dracut/modules.d. This option forces dracut to only include the specified dracut modules. In most cases the --add option is what you want to use. --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. -d, --drivers [LIST] Specify a space-separated list of kernel modules to exclusively include in 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 colon-separated list of directories where to look for firmware files. --libdirs [LIST] Specify a space-separated list of directories where to look for libraries. --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. Despite its name, this command only sets initrd parameters. --strip Strip binaries in the initramfs. --aggressive-strip Strip more than just debug symbol and sections, for a smaller initramfs build. The --strip option must also be specified. --nostrip Do not strip 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 file. --nomdadmconf Do not include local /etc/mdadm.conf file. --lvmconf Include local /etc/lvm/lvm.conf file. --nolvmconf Do not include local /etc/lvm/lvm.conf file. --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 --add-confdir [DIR] Add an extra configuration directory to use *.conf files from. If the directory is not existed, will look for subdirectory under confdir. --tmpdir [DIR] Temporary directory to be used instead of default ${TMPDIR:-/var/tmp}. -r, --sysroot [DIR] Specify sysroot directory to collect files from. -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 host-only mode to use. [MODE] could be one of "sloppy" or "strict". "sloppy" mode is used by default. In "sloppy" host-only mode, extra drivers and modules will be installed, so minor hardware change won't make the image unbootable (e.g. 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. --hostonly-nics [LIST] Only enable listed NICs in the initramfs. The list can be empty, so other modules can install only the necessary network drivers. --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"), or "mapper" to use /dev/mapper device names (default). --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. --mount "[MP]" Same as above, but [DEV], [FSTYPE] and [FSOPTS] are determined by looking at the current mounts. --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. --remove [LIST] Remove a space-separated list of files and directories from the initramfs (supports globbing). --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. --zstd Compress the generated initramfs using Zstandard. Make sure that your kernel has zstd 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. --compress-level [LEVEL] Compression level passed to compression program. --no-compress Do not compress the generated initramfs. This will override any other compression options. --squash-compressor [COMPRESSION] Specify the compressor and compressor specific options used by mksquashfs if squash module is called when building the initramfs. --enhanced-cpio Attempt to reflink cpio file data using 3cpio/dracut-cpio. --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. --printconfig Print the computed configuration and exit. --sshkey [SSHKEY] Add SSH key to initramfs (use with ssh-client module). --logfile [FILE] Logfile to use (overrides configuration setting). --reproducible Create reproducible images. --no-reproducible Do not create reproducible images. --loginstall [DIR] Log all files installed from the host to [DIR]. --uefi Create an UEFI executable with the kernel cmdline and kernel combined. --ukify Enables ukify. --no-uefi Disables UEFI mode. --no-ukify Disables ukify. --no-machineid Affects the default output filename of the UEFI executable, discarding the part. --uefi-stub [FILE] Use the UEFI stub [FILE] to create an UEFI executable. --uefi-splash-image [FILE] Use [FILE] as a splash image when creating an UEFI executable. Requires bitmap (.bmp) image format. --kernel-image [FILE] Location of the kernel image. --sbat [PARAMETERS] The SBAT parameters to be added to .sbat. The string "sbat,1,SBAT Version,sbat,1, https://github.com/rhboot/shim/blob/main/SBAT.md" is already added by default. --regenerate-all Regenerate all initramfs images at the default location for the kernel versions found on the system. -p, --parallel Use parallel processing if possible (currently only supported --regenerate-all) images simultaneously. --version Display version. If [LIST] has multiple arguments, then you have to put these in quotes. For example: # dracut --add-drivers "module1 module2" ...
