==============
: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.
