Example base configuration files

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

I don't know which list this really belongs on.

I've stumbled over the fact that example/vanilla configuration files for base 
programs seem to be inconsistently spread across /etc (thus, the etc set) and 
/usr/share/examples (thus, the misc set).

Most (of those I've inspected) are in /etc, rtadvd.conf is in examples only,
and postfix is in both of them.

Is there any hidden (to me) scheme behind that?
