Recently I ordered a server with Debian etch. Unfortunately during testing I noticed that startx was on the system, along with a whole slew of other junk that I don’t generally want on a fresh server. I wanted to remove all of the cruft but I didn’t have the exact package list.
The solution was to run tasksel. I then saw that Desktop, Mail, and Print server were all selected. I deselected all of them but then I still had all the crufty config files lying around. Whats the best way to remove all those config files from packages you don’t exactly know were on there?

aptitude purge ~c
