For daemons which have a main configuration file, there's little reason for the administrator to use configuration snippets. They are useful for packagers which need to override settings, but we shouldn't advertise that as the main way of configuring those services. https://bugs.freedesktop.org/show_bug.cgi?id=89397

Any per-interface NTP servers obtained from

instead.</para></listitem>
