|
1 - only fatal errors |
|
2 - all errors |
|
3 - warnings |
|
4 - info (default) |
|

--tmpdir [DIR] Temporary directory to be used instead of default |
|
/var/tmp. |
|
-l, --local Local mode. Use modules from the current working |
|
directory instead of the system-wide installed in |
|
/usr/lib/dracut/modules.d. |
|
Useful when running dracut from a git checkout. |
|
-H, --hostonly Host-Only mode: Install only what is needed for |
|
booting the local host instead of a generic host. |

If SOURCE is a file, it will be installed to TARGET |
|
in the final initramfs. |
|
-I, --install [LIST] Install the space separated list of files into the |
|
initramfs. |
|
--gzip Compress the generated initramfs using gzip. |
|
This will be done by default, unless another |
|
compression option or --no-compress is passed. |
|
--bzip2 Compress the generated initramfs using bzip2. |
|
Make sure your kernel has bzip2 decompression support |
|
compiled in, otherwise you will not be able to boot. |
|
--lzma Compress the generated initramfs using lzma. |
|
Make sure your kernel has lzma support compiled in, |
|
otherwise you will not be able to boot. |
|
--xz Compress the generated initramfs using xz. |
|
Make sure that your kernel has xz support compiled |
|
in, otherwise you will not be able to boot. |
|
--compress [COMPRESSION] Compress the generated initramfs with the |
|
passed compression program. Make sure your kernel |
|
knows how to decompress the generated initramfs, |
|
otherwise you will not be able to boot. |
|
--no-compress Do not compress the generated initramfs. This will |
|
override any other compression options. |
|
--list-modules List all available dracut modules. |
|
-M, --show-modules Print included module's name to standard output during |
|
build. |

|
|
|
If [LIST] has multiple arguments, then you have to put these in quotes. |
|
For example: |
|
# dracut --add-drivers "module1 module2" ... |
