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.
