139 -c, --conf [FILE] Specify configuration file to use.
140 Default: /etc/dracut.conf
141 --confdir [DIR] Specify configuration directory to use *.conf files
142 from. Default: /etc/dracut.conf.d
143 --tmpdir [DIR] Temporary directory to be used instead of default
145 -r, --sysroot [DIR] Specify sysroot directory to collect files from.
146 -l, --local Local mode. Use modules from the current working
147 directory instead of the system-wide installed in
148 /usr/lib/dracut/modules.d.
149 Useful when running dracut from a git checkout.
150 -H, --hostonly Host-Only mode: Install only what is needed for
151 booting the local host instead of a generic host.
152 -N, --no-hostonly Disables Host-Only mode
153 --hostonly-mode <mode>
154 Specify the hostonly mode to use. <mode> could be
155 one of "sloppy" or "strict". "sloppy" mode is used
157 In "sloppy" hostonly mode, extra drivers and modules
158 will be installed, so minor hardware change won't make
159 the image unbootable (eg. changed keyboard), and the
160 image is still portable among similar hosts.
161 With "strict" mode enabled, anything not necessary
162 for booting the local host in its current state will
163 not be included, and modules may do some extra job
164 to save more space. Minor change of hardware or
165 environment could make the image unbootable.
166 DO NOT use "strict" mode unless you know what you
168 --hostonly-cmdline Store kernel command line arguments needed
170 --no-hostonly-cmdline Do not store kernel command line arguments needed
172 --no-hostonly-default-device
173 Do not generate implicit host devices like root,
174 swap, fstab, etc. Use "--mount" or "--add-device"
175 to explicitly add devices as needed.
176 --hostonly-i18n Install only needed keyboard and font files according
177 to the host configuration (default).
178 --no-hostonly-i18n Install all keyboard and font files available.
179 --hostonly-nics [LIST]
180 Only enable listed NICs in the initramfs.
181 --persistent-policy [POLICY]
182 Use [POLICY] to address disks and partitions.
183 POLICY can be any directory name found in /dev/disk.
184 E.g. "by-uuid", "by-label"
185 --fstab Use /etc/fstab to determine the root device.
186 --add-fstab [FILE] Add file to the initramfs fstab
187 --mount "[DEV] [MP] [FSTYPE] [FSOPTS]"
188 Mount device [DEV] on mountpoint [MP] with filesystem
189 [FSTYPE] and options [FSOPTS] in the initramfs
190 --mount "[MP]" Same as above, but [DEV], [FSTYPE] and [FSOPTS] are
191 determined by looking at the current mounts.
192 --add-device "[DEV]" Bring up [DEV] in initramfs
193 -i, --include [SOURCE] [TARGET]
194 Include the files in the SOURCE directory into the
195 Target directory in the final initramfs.
196 If SOURCE is a file, it will be installed to TARGET
197 in the final initramfs.
198 -I, --install [LIST] Install the space separated list of files into the
200 --install-optional [LIST] Install the space separated list of files into the
201 initramfs, if they exist.
202 --gzip Compress the generated initramfs using gzip.
203 This will be done by default, unless another
204 compression option or --no-compress is passed.
205 --bzip2 Compress the generated initramfs using bzip2.
206 Make sure your kernel has bzip2 decompression support
207 compiled in, otherwise you will not be able to boot.
208 --lzma Compress the generated initramfs using lzma.
209 Make sure your kernel has lzma support compiled in,
210 otherwise you will not be able to boot.
211 --xz Compress the generated initramfs using xz.
212 Make sure that your kernel has xz support compiled
213 in, otherwise you will not be able to boot.
214 --lzo Compress the generated initramfs using lzop.
215 Make sure that your kernel has lzo support compiled
216 in, otherwise you will not be able to boot.
217 --lz4 Compress the generated initramfs using lz4.
218 Make sure that your kernel has lz4 support compiled
219 in, otherwise you will not be able to boot.
220 --zstd Compress the generated initramfs using Zstandard.
221 Make sure that your kernel has zstd support compiled
222 in, otherwise you will not be able to boot.
223 --compress [COMPRESSION] Compress the generated initramfs with the
224 passed compression program. Make sure your kernel
225 knows how to decompress the generated initramfs,
226 otherwise you will not be able to boot.
227 --no-compress Do not compress the generated initramfs. This will
228 override any other compression options.
229 --enhanced-cpio Attempt to reflink cpio file data using dracut-cpio.
230 --list-modules List all available dracut modules.
231 -M, --show-modules Print included module's name to standard output during
233 --keep Keep the temporary initramfs for debugging purposes
234 --printsize Print out the module install size
235 --sshkey [SSHKEY] Add ssh key to initramfs (use with ssh-client module)
236 --logfile [FILE] Logfile to use (overrides configuration setting)
237 --reproducible Create reproducible images
238 --no-reproducible Do not create reproducible images
239 --loginstall [DIR] Log all files installed from the host to [DIR]
240 --uefi Create an UEFI executable with the kernel cmdline and
242 --no-uefi Disables UEFI mode
243 --uefi-stub [FILE] Use the UEFI stub [FILE] to create an UEFI executable
244 --uefi-splash-image [FILE]
245 Use [FILE] as a splash image when creating an UEFI
247 --kernel-image [FILE] location of the kernel image
248 --regenerate-all Regenerate all initramfs images at the default location
249 for the kernel versions found on the system
250 --version Display version
252 If [LIST] has multiple arguments, then you have to put these in quotes.
