<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>/usr/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 overridden 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>
