60 | identify and compare configuration files in | |
61 | <filename>/etc</filename> that override default | |
62 | counterparts in <filename>/usr</filename>. The command | |
63 | line argument can be one or more name of a subdirectories of | |
64 | <filename>/etc</filename> or | |
65 | <filename>/usr/lib</filename> to compare, such as | |
66 | <filename>tmpfiles.d</filename>, <filename>sysctl.d</filename> or | |
67 | <filename>systemd/system</filename>.</para> | |
68 | ||
69 | <para>When no argument is specified a number of | |
