For example, an apache update MAY require that I first check what it
will do to http.conf. First install it on a test server, check out what
is new, then apply it. Or a firefox update, and I only run firefox
anymore on the server when I am running in via vnc, and probably will
never again (after setup) run firefox, so I will apply that update when
I don't have something more to do. I see mysqld on my DNS server, but I
have it off. Also cups is there, and I don't do printing. I have not
uninstalled these, so if they get updates, I will apply them, but not
when I am on the road. Now a bind or apache security update will get
applied....
yes, I still tend to install desktop on my servers to get them
configured, the set inittab to 3 and will rarely ever run desktop again.

I am on it, and I do look at the announcements. Still which rpm is used
on which server? What is critical and what is not?
