 129                          1 - only fatal errors
 130                          2 - all errors
 131                          3 - warnings

 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.

 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

 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.
