I already experimented with /usr/share/factory/{etc,var} , but /usr/etc sounds
fine to me, too.
Additionally I would like to have that in the rpm package itsself, not with
some plugin on installation, because "rpm -qf" should output to which package
the file in /usr/etc belongs. Also the %config(noreplace) attribute has to be
removed from the pristine config files.
Attached is a quick hack to rpm I have done for experimenting with that feature.
