+
+ <para><command>systemd-delta</command> may be used to identify and
+ compare configuration files that override other configuration
+ files. Files in <filename>/etc</filename> have highest priority,
+ files in <filename>/run</filename> have the second highest
+ priority, ..., files in <filename>/lib</filename> have lowest
+ priority. Files in a directory with higher priority override files
+ with the same name in directories of lower priority. In addition,
+ certain configuration files can have <literal>.d</literal>
+ directories which contain "drop-in" files with configuration
+ snippets which augment the main configuration file. "Drop-in"
+ files can be overriden in the same way by placing files with the
+ same name in a directory of higher priority (except that in case
+ of "drop-in" files, both the "drop-in" file name and the name of
+ the containing directory, which corresponds to the name of the
+ main configuration file, must match). For a fuller explanation,
+ see
+ <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
+ </para>
+
+ <para>The command line argument will be split into a prefix and a
+ suffix. Either is optional. The prefix must be one of the
+ directories containing configuration files
+ (<filename>/etc</filename>, <filename>/run</filename>,
+ <filename>/usr/lib</filename>, ...). If it is given, only
+ overriding files contained in this directory will be shown.
+ Otherwise, all overriding files will be shown. The suffix must be
+ a name of a subdirectory containing configuration files like
+ <filename>tmpfiles.d</filename>, <filename>sysctl.d</filename> or
+ <filename>systemd/system</filename>. If it is given, only
+ configuration files in this subdirectory (across all configuration
+ paths) will be analyzed. Otherwise, all configuration files will
+ be analyzed. If the command line argument is not given at all, all
+ configuration files will be analyzed. See below for some
+ examples.</para>
