stop that trolling

*local* CONFIGURATIONS belong to /etc and nothing else

Lennarts point is that any defaults and package data don't belong there 
and he is not completly wrong in that context - in the best case you 
would have a operating system with *nothing* in /etc and any package 
shipped stuff can have a *override* file with the same name in /etc

at the end this would also obsolete all that rpmnew / rpmsave stuff just 
because files from packages would no longer be touched by a user but 
*completly* ignored from the moment there is a replacement in /etc
