I'm considering using RH's User Private Groups scheme for a LFS project I'm starting.............

I have no experience with UPGs and would like to know from other users who are familar with it what's good or bad about it..........

I've read the RedHat manuals, know how to set it up and understand their rationale behind it, but in the real world there's always some gothchas......

So if you could cast your vote, relate your experiences with using UPGs, whether it's a good idea or a bad one and if you like it or not, I would be most grateful (and possibly others would be grateful, too).............

Thanx,
