That's no big deal; with a script of of mine I normally would be able to do it in one or two minutes for that machine. I would, if there wasn't dovecot.conf and squid.conf. They have lots of comments in them that explain nearly each of the settings. That just sucks because I now have to look over all of them :-((
Especially dovecot.conf is bad:
[thl@truhe etc]$ diff -u dovecot.conf dovecot.conf.rpmnew | grep '^+' | wc -l
[thl@truhe etc]$ diff -u dovecot.conf dovecot.conf.rpmnew | grep '^+' | grep '#' | wc -l
Most of those eight non-comment lines are probably settings I actually did.
