<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).
|
|

|
</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>
