Hi,

Personally I enable nightly updates but disable the updating of certain
packages (services) that the server provides. For this I use the
'exclude' statement in the /etc/yum.conf file. On all servers I include
excluding the kernel and glibc. If these are to be upgraded, and require
a reboot, then I'll do them when it is convenient to me. Other services,
such as exim (MTA), freeradius (RADIUS), squid (web cache), etc are
likewise disabled on the relevant servers. Again, if they are to be
upgraded, then I will do them when it is convenient and without
disrupting the current service.
