175 Target directory in the final initramfs.
176 If SOURCE is a file, it will be installed to TARGET
177 in the final initramfs.
178 -I, --install [LIST] Install the space separated list of files into the
180 --install-optional [LIST] Install the space separated list of files into the

185 --bzip2 Compress the generated initramfs using bzip2.
186 Make sure your kernel has bzip2 decompression support
187 compiled in, otherwise you will not be able to boot.

198 Make sure that your kernel has lz4 support compiled
199 in, otherwise you will not be able to boot.
200 --zstd Compress the generated initramfs using Zstandard.
201 Make sure that your kernel has zstd support compiled
202 in, otherwise you will not be able to boot.
203 --compress [COMPRESSION] Compress the generated initramfs with the
204 passed compression program. Make sure your kernel
205 knows how to decompress the generated initramfs,
206 otherwise you will not be able to boot.
207 --no-compress Do not compress the generated initramfs. This will
208 override any other compression options.
209 --list-modules List all available dracut modules.
210 -M, --show-modules Print included module's name to standard output during
212 --keep Keep the temporary initramfs for debugging purposes
213 --printsize Print out the module install size
214 --sshkey [SSHKEY] Add ssh key to initramfs (use with ssh-client module)
215 --logfile [FILE] Logfile to use (overrides configuration setting)
216 --reproducible Create reproducible images
217 --no-reproducible Do not create reproducible images
218 --loginstall [DIR] Log all files installed from the host to [DIR]
