DRACUT.CONF(5)
==============
:doctype: manpage
:man source: dracut
:man manual: dracut
NAME
----
dracut.conf - configuration file(s) for dracut
SYNOPSIS
--------
_/etc/dracut.conf_ _/etc/dracut.conf.d/*.conf_ _/usr/lib/dracut/dracut.conf.d/*.conf_
Description
-----------
_dracut.conf_ is loaded during the initialisation phase of dracut. Command line
parameter will overwrite any values set here.
_*.conf_ files are read from /usr/lib/dracut/dracut.conf.d and /etc/dracut.conf.d.
Files with the same name in /etc/dracut.conf.d will replace files in /usr/lib/dracut/dracut.conf.d.
The files are then read in alphanumerical order and will overwrite parameters set in
_/etc/dracut.conf_. Each line specifies an attribute and a value. A '#'
indicates the beginning of a comment; following characters, up to the end of the
line are not interpreted.
dracut command line options will overwrite any values set here.
Configuration files must have the extension .conf; other extensions are ignored.

*omit_dracutmodules+=*" __<dracut modules>__ "::
Omit a space-separated list of dracut modules.
*add_dracutmodules+=*" __<dracut modules>__ "::
Add a space-separated list of dracut modules.

initramfs. The kernel modules have to be specified without the ".ko" suffix.
*filesystems+=*" __<filesystem names>__ "::
Specify a space-separated list of kernel filesystem modules to exclusively
include in the generic initramfs.
*drivers_dir=*"__<kernel modules directory>__"::
Specify the directory, where to look for kernel modules
