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