+Version: $DRACUT_VERSION
+
+Creates initial ramdisk images for preloading modules
+
+ --kver [VERSION] Set kernel version to [VERSION].
-f, --force Overwrite existing initramfs file.
-m, --modules [LIST] Specify a space-separated list of dracut modules to
call when building the initramfs. Modules are located
--no-kernel Do not install kernel drivers and firmware files
--strip Strip binaries in the initramfs
--nostrip Do not strip binaries in the initramfs (default)
+ --hardlink Hardlink files in the initramfs (default)
+ --nohardlink Do not hardlink files in the initramfs
--prefix [DIR] Prefix initramfs files with [DIR]
--noprefix Do not prefix initramfs files (default)
--mdadmconf Include local /etc/mdadm.conf
--nolvmconf Do not include local /etc/lvm/lvm.conf
--fscks [LIST] Add a space-separated list of fsck helpers.
--nofscks Inhibit installation of any fsck helpers.
+ --ro-mnt Mount / and /usr read-only by default.
-h, --help This message
--debug Output debug information of the build process
--profile Output profile information of the build process
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.
- --no-hostonly Disables Host-Only mode
+ -N, --no-hostonly Disables Host-Only mode
--fstab Use /etc/fstab to determine the root device.
--add-fstab [FILE] Add file to the initramfs fstab
--mount "[DEV] [MP] [FSTYPE] [FSOPTS]"
Mount device [DEV] on mountpoint [MP] with filesystem
[FSTYPE] and options [FSOPTS] in the initramfs
+ --device "[DEV]" Bring up [DEV] in initramfs
-i, --include [SOURCE] [TARGET]
Include the files in the SOURCE directory into the
Target directory in the final initramfs.
--sshkey [SSHKEY] Add ssh key to initramfs (use with ssh-client module)
If [LIST] has multiple arguments, then you have to put these in quotes.

For example:
-# dracut --add-drivers "module1 module2" ...
