a0120420 147 -r, --sysroot [DIR] Specify sysroot directory to collect files from.
5616feb0
AT		 148 -l, --local Local mode. Use modules from the current working
149 directory instead of the system-wide installed in
c5a65990 150 /usr/lib/dracut/modules.d.
5616feb0 151 Useful when running dracut from a git checkout.
7c179686 152 -H, --hostonly Host-Only mode: Install only what is needed for
324ea606 153 booting the local host instead of a generic host.
472189da 154 -N, --no-hostonly Disables Host-Only mode
a695250e
KS		 155 --hostonly-mode <mode>
156 Specify the hostonly mode to use. <mode> could be
157 one of "sloppy" or "strict". "sloppy" mode is used
158 by default.
159 In "sloppy" hostonly mode, extra drivers and modules
160 will be installed, so minor hardware change won't make
161 the image unbootable (eg. changed keyboard), and the
162 image is still portable among similar hosts.
163 With "strict" mode enabled, anything not necessary
164 for booting the local host in its current state will
165 not be included, and modules may do some extra job
166 to save more space. Minor change of hardware or
167 environment could make the image unbootable.
168 DO NOT use "strict" mode unless you know what you
169 are doing.

3b403b32 227 knows how to decompress the generated initramfs,
5e6c3b03 228 otherwise you will not be able to boot.
5b158ad3 229 --no-compress Do not compress the generated initramfs. This will
