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.
