36 | <title>Description</title> | |
37 | ||
38 | <para><command>systemd-delta</command> may be used to identify and | |
39 | compare configuration files that override other configuration | |
40 | files. Files in <filename>/etc</filename> have highest priority, | |
41 | files in <filename>/run</filename> have the second highest | |
83ddf5d3 | 42 | priority, …, files in <filename>/usr/lib</filename> have lowest |
798d3a52 ZJS |
43 | priority. Files in a directory with higher priority override files |
44 | with the same name in directories of lower priority. In addition, | |
45 | certain configuration files can have <literal>.d</literal> | |
46 | directories which contain "drop-in" files with configuration | |
47 | snippets which augment the main configuration file. "Drop-in" | |
ff9b60f3 | 48 | files can be overridden in the same way by placing files with the |
b938cb90 | 49 | same name in a directory of higher priority (except that, in case |
798d3a52 ZJS |
50 | of "drop-in" files, both the "drop-in" file name and the name of |
51 | the containing directory, which corresponds to the name of the | |
52 | main configuration file, must match). For a fuller explanation, | |
53 | see | |
54 | <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>. | |
55 | </para> | |
56 | ||
57 | <para>The command line argument will be split into a prefix and a | |
58 | suffix. Either is optional. The prefix must be one of the | |
59 | directories containing configuration files | |
60 | (<filename>/etc</filename>, <filename>/run</filename>, | |
1eecafb8 | 61 | <filename>/usr/lib</filename>, …). If it is given, only |
798d3a52 ZJS |
62 | overriding files contained in this directory will be shown. |
63 | Otherwise, all overriding files will be shown. The suffix must be | |
64 | a name of a subdirectory containing configuration files like | |
65 | <filename>tmpfiles.d</filename>, <filename>sysctl.d</filename> or | |
66 | <filename>systemd/system</filename>. If it is given, only | |
67 | configuration files in this subdirectory (across all configuration | |
68 | paths) will be analyzed. Otherwise, all configuration files will | |
69 | be analyzed. If the command line argument is not given at all, all | |
70 | configuration files will be analyzed. See below for some | |
71 | examples.</para> | |
