I do tend to pick and choose which updates to install, I just like
having the availability of an update system so that if there is a patch
that really NEEDS to be installed, and I don't have the time or
opportunity to do it manually, there's a quick way of doing it.

Actually, I usually install a core system (everything basically to make
it work at all), and then I'll compile my own apache, mysql, etc.  That
way I'm not linked to the version the vendor thinks is the best.  But
the base utils, and os stuff I usually stick with the distribution and
let it's update system do the work.

I had seen your comment about RHEL3 and the perl problem.  It's one of
the things that made me start looking elsewhere (I was looking into
White Hat at the time, so I figured it had the same problem).  I use
perl A LOT, and while I can compile my own and all that, I figure it's a
basic part of a distribution now, and if the distribution can't get it
right, something's wrong.  :)

I understand that!  That's the problem I'm in now.  Most of these
servers we had just put in 2 months before Red Hat switched there plan.
It's not a huge issue (I can always install something else), but half
these servers are out of town, so it becomes more of a pain.  What ever
I choose this time, I want to be around for awhile.  That's why I had
looked into LFS, because I controlled it then.  But that's a lot of
work.
