- <title>Description</title>
-
- <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>
