Hi all,

Here in my department, we break errata up into 3 groups:

Monthly: For things that require either an X-Windows restart, or a
          system restart.  Happens on the first Tuesday of the month.
Weekly:  Pretty much anything else.  Happens every Tuesday.
Daily:   Emergency items to push out.  Rarely used.

I've always been of the feeling that you only need to reboot when 
there's a kernel upgrade (perhaps glibc, too?), and that you only need 
to restart X when there's an upgrade to x.org.

I want to ask: how true is this?  Is it safe to do a gnome, dbus, etc 
(Normally I'd put these in the 'weekly' repository) upgrade while the 
user is logged in, and we don't know when they'll log out next?  I 
wonder about settings, etc getting corrupted as a result of this, as 
well as erratic behavior.

The above system has served us well in the past, but as we're rolling 
out SL4, I just want to make sure that I'm doing it as best as I can.

Thanks for any insights & tips,
Erik.
