78 Creates initial ramdisk images for preloading modules
80 --kver [VERSION] Set kernel version to [VERSION].
81 -f, --force Overwrite existing initramfs file.
82 [OUTPUT_FILE] --rebuild
83 Append the current arguments to those with which the
84 input initramfs image was built. This option helps in

93 -m, --modules [LIST] Specify a space-separated list of dracut modules to
94 call when building the initramfs. Modules are located

96 This option forces dracut to only include the specified
98 In most cases the --add option is what you want to use.

100 modules to add to the initramfs.
101 --force-drivers [LIST]

124 --kernel-cmdline [PARAMETERS]
125 Specify default kernel command line parameters.
126 --strip Strip binaries in the initramfs.
127 --aggressive-strip Strip more than just debug symbol and sections,
128 for a smaller initramfs build. The --strip option must
130 --nostrip Do not strip binaries in the initramfs.
131 --hardlink Hardlink files in the initramfs.

153 -v, --verbose Increase verbosity level.
154 -q, --quiet Decrease verbosity level.
155 -c, --conf [FILE] Specify configuration file to use.
156 Default: /etc/dracut.conf
157 --confdir [DIR] Specify configuration directory to use *.conf files
158 from. Default: /etc/dracut.conf.d
159 --tmpdir [DIR] Temporary directory to be used instead of default
161 -r, --sysroot [DIR] Specify sysroot directory to collect files from.
162 -l, --local Local mode. Use modules from the current working

166 -H, --hostonly Host-only mode: Install only what is needed for
167 booting the local host instead of a generic host.
168 -N, --no-hostonly Disables host-only mode.
169 --hostonly-mode [MODE]
170 Specify the host-only mode to use. [MODE] could be
171 one of "sloppy" or "strict". "sloppy" mode is used
173 In "sloppy" host-only mode, extra drivers and modules
174 will be installed, so minor hardware change won't make
175 the image unbootable (e.g. changed keyboard), and the
176 image is still portable among similar hosts.
177 With "strict" mode enabled, anything not necessary
178 for booting the local host in its current state will
179 not be included, and modules may do some extra job
180 to save more space. Minor change of hardware or
181 environment could make the image unbootable.
182 DO NOT use "strict" mode unless you know what you
184 --hostonly-cmdline Store kernel command line arguments needed
186 --no-hostonly-cmdline Do not store kernel command line arguments needed
188 --no-hostonly-default-device
189 Do not generate implicit host devices like root,
190 swap, fstab, etc. Use "--mount" or "--add-device"
191 to explicitly add devices as needed.
192 --hostonly-i18n Install only needed keyboard and font files according
193 to the host configuration (default).
194 --no-hostonly-i18n Install all keyboard and font files available.
195 --hostonly-nics [LIST]
196 Only enable listed NICs in the initramfs. The list can
197 be empty, so other modules can install only the
198 necessary network drivers.
199 --persistent-policy [POLICY]
200 Use [POLICY] to address disks and partitions.
201 POLICY can be any directory name found in /dev/disk.
202 E.g. "by-uuid", "by-label"
203 --fstab Use /etc/fstab to determine the root device.
204 --add-fstab [FILE] Add file to the initramfs fstab.
205 --mount "[DEV] [MP] [FSTYPE] [FSOPTS]"
206 Mount device [DEV] on mountpoint [MP] with filesystem
207 [FSTYPE] and options [FSOPTS] in the initramfs.
208 --mount "[MP]" Same as above, but [DEV], [FSTYPE] and [FSOPTS] are
209 determined by looking at the current mounts.
210 --add-device "[DEV]" Bring up [DEV] in initramfs.
211 -i, --include [SOURCE] [TARGET]
212 Include the files in the SOURCE directory into the
213 Target directory in the final initramfs.
214 If SOURCE is a file, it will be installed to TARGET
215 in the final initramfs.
216 -I, --install [LIST] Install the space separated list of files into the
218 --install-optional [LIST]
219 Install the space separated list of files into the
220 initramfs, if they exist.
221 --gzip Compress the generated initramfs using gzip.
222 This will be done by default, unless another
223 compression option or --no-compress is passed.
224 --bzip2 Compress the generated initramfs using bzip2.
225 Make sure your kernel has bzip2 decompression support
226 compiled in, otherwise you will not be able to boot.
227 --lzma Compress the generated initramfs using lzma.
228 Make sure your kernel has lzma support compiled in,
229 otherwise you will not be able to boot.
230 --xz Compress the generated initramfs using xz.
231 Make sure that your kernel has xz support compiled
232 in, otherwise you will not be able to boot.
233 --lzo Compress the generated initramfs using lzop.
234 Make sure that your kernel has lzo support compiled
235 in, otherwise you will not be able to boot.
236 --lz4 Compress the generated initramfs using lz4.
237 Make sure that your kernel has lz4 support compiled
238 in, otherwise you will not be able to boot.
239 --zstd Compress the generated initramfs using Zstandard.
240 Make sure that your kernel has zstd support compiled
241 in, otherwise you will not be able to boot.
242 --compress [COMPRESSION]
243 Compress the generated initramfs with the
244 passed compression program. Make sure your kernel
245 knows how to decompress the generated initramfs,
246 otherwise you will not be able to boot.
247 --no-compress Do not compress the generated initramfs. This will
248 override any other compression options.
249 --squash-compressor [COMPRESSION]
250 Specify the compressor and compressor specific options
251 used by mksquashfs if squash module is called when
252 building the initramfs.
253 --enhanced-cpio Attempt to reflink cpio file data using dracut-cpio.
254 --list-modules List all available dracut modules.
255 -M, --show-modules Print included module's name to standard output during
257 --keep Keep the temporary initramfs for debugging purposes.
258 --printsize Print out the module install size.
259 --sshkey [SSHKEY] Add SSH key to initramfs (use with ssh-client module).
260 --logfile [FILE] Logfile to use (overrides configuration setting).
261 --reproducible Create reproducible images.
262 --no-reproducible Do not create reproducible images.
263 --loginstall [DIR] Log all files installed from the host to [DIR].
264 --uefi Create an UEFI executable with the kernel cmdline and
266 --no-uefi Disables UEFI mode.
267 --no-machineid Affects the default output filename of the UEFI
268 executable, discarding the <MACHINE_ID> part.
269 --uefi-stub [FILE] Use the UEFI stub [FILE] to create an UEFI executable.
270 --uefi-splash-image [FILE]
271 Use [FILE] as a splash image when creating an UEFI
272 executable. Requires bitmap (.bmp) image format.
273 --kernel-image [FILE] Location of the kernel image.
274 --regenerate-all Regenerate all initramfs images at the default location
275 for the kernel versions found on the system.
276 -p, --parallel Use parallel processing if possible (currently only
277 supported --regenerate-all)
278 images simultaneously.
279 --version Display version.
281 If [LIST] has multiple arguments, then you have to put these in quotes.
