<title>Configuration Format</title>
+ <para>Each configuration file is named in the style of
+ <filename><program>.conf</filename>.
+ Files in <filename>/etc/</filename> overwrite
+ files with the same name in <filename>/usr/lib/</filename>.
+ Files in <filename>/run</filename> overwrite files with
+ the same name in <filename>/etc/</filename> and
+ <filename>/usr/lib/</filename>. Packages should install their
+ configuration files in <filename>/usr/lib/</filename>, files
+ in <filename>/etc/</filename> are reserved for the local
+ administration, which possibly decides to overwrite the
+ configurations installed from packages. All files are sorted
+ by filename in alphabetical order, regardless in which of the
+ directories they reside, to ensure that a specific
+ configuration file takes precedence over another file with
+ an alphabetically later name.</para>

<para>The configuration format is one line per path
containing action, mode, ownership and age
fields:</para>

- <para>If multiple integers and units are specified the time values are summed up.</para>

- <para>The age field only applies to lines starting with d, D and x. If omitted or set to - no automatic clean-up is done.</para>
