That was in response to an earlier poster's comment wondering why anyone
would expect installing exim to work if there was a user account named
exim.  It's hard to know in advance which packages will create users; I've

It's not that it's a common occurance, since most program names don't
happen to match people names.  It's that when it *does* happen, there
aren't a lot of good ways of dealing with it, and sooner or later it will
