Subject: [PATCH] Do not advertise .d snippets over main config file

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.
