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 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).
