thank you for the pointers to the wikipages. how is the current status 
of adoption of Config::Model in Debian? the wikipage states that it's a 
proposal.

while reading about PackageConfigUpgrade, i realized that i don't get 
those questions about modified config files in ubuntu. does anybody know 
how configuration upgrades/merges are handled there?

thanks,
michael
