+
+ <para>Configuration files are read from directories in
+ <filename>/etc/</filename>, <filename>/run/</filename>, and
+ <filename>/usr/lib/</filename>, in order of precedence.
+ Each configuration file in these configuration directories shall be named in
+ the style of <filename><replaceable>filename</replaceable>.conf</filename>.
+ Files in <filename>/etc/</filename> override files with the same name in
+ <filename>/run/</filename> and <filename>/usr/lib/</filename>. Files in
+ <filename>/run/</filename> override files with the same name in
+ <filename>/usr/lib/</filename>.</para>
+
+ <para>Packages should install their configuration files in
+ <filename>/usr/lib/</filename>. Files in <filename>/etc/</filename> are
+ reserved for the local administrator, who may use this logic to override the
+ configuration files installed by vendor packages. All configuration files
+ are sorted by their filename in lexicographic order, regardless of which of
+ the directories they reside in. If multiple files specify the same option,
+ the entry in the file with the lexicographically latest name will take
+ precedence. It is recommended to prefix all filenames with a two-digit number
+ and a dash, to simplify the ordering of the files.</para>
+
+ <para>If the administrator wants to disable a configuration file supplied by
+ the vendor, the recommended way is to place a symlink to
+ <filename>/dev/null</filename> in the configuration directory in
+ <filename>/etc/</filename>, with the same filename as the vendor
+ configuration file.</para>

+ <title>Configuration Directories and Precedence</title>
+
+ <para>Default configuration is defined during compilation, so a
+ configuration file is only needed when it is necessary to deviate
+ from those defaults. By default the configuration file in
+ <filename>/etc/systemd/</filename> contains commented out entries
+ showing the defaults as a guide to the administrator. This file
+ can be edited to create local overrides.
+ </para>
+
+ <para>When packages need to customize the configuration, they can
+ install configuration snippets in
+ <filename>/usr/lib/systemd/*.conf.d/</filename>. Files in
+ <filename>/etc/</filename> are reserved for the local
+ administrator, who may use this logic to override the
+ configuration files installed by vendor packages. The main
+ configuration file is read before any of the configuration
+ directories, and has the lowest precedence; entries in a file in
+ any configuration directory override entries in the single
+ configuration file. Files in the
+ <filename>*.conf.d/</filename> configuration subdirectories
+ are sorted by their filename in lexicographic order, regardless of
+ which of the subdirectories they reside in. If multiple files
+ specify the same option, the entry in the file with the
+ lexicographically latest name takes precedence. It is recommended
+ to prefix all filenames in those subdirectories with a two-digit
+ number and a dash, to simplify the ordering of the files.</para>
+
+ <para>To disable a configuration file supplied by the vendor, the
+ recommended way is to place a symlink to
+ <filename>/dev/null</filename> in the configuration directory in
+ <filename>/etc/</filename>, with the same filename as the vendor
+ configuration file.</para>
