  11 SYNOPSIS
  12 --------
  13 _/etc/dracut.conf_ _/etc/dracut.conf.d/*.conf_  _/usr/lib/dracut/dracut.conf.d/*.conf_
  14
  15 Description
  16 -----------
  17 _dracut.conf_ is loaded during the initialisation phase of dracut. Command line
  18 parameter will overwrite any values set here.
  19
  20 _*.conf_ files are read from /usr/lib/dracut/dracut.conf.d and /etc/dracut.conf.d.
  21 Files with the same name in /etc/dracut.conf.d will replace files in /usr/lib/dracut/dracut.conf.d.
  22 The files are then read in alphanumerical order and will overwrite parameters set in
  23 _/etc/dracut.conf_. Each line specifies an attribute and a value. A '#'
  24 indicates the beginning of a comment; following characters, up to the end of the
  25 line are not interpreted.
  26
  27 dracut command line options will overwrite any values set here.
  28
  29 Configuration files must have the extension .conf; other extensions are ignored.

 139 -----
 140 _/etc/dracut.conf_::

 145     Any _/etc/dracut.conf.d/*.conf_ file can overwrite the values in
