However, if you want (or need) to track stable, there are
certain possibilities to avoid trouble. Of course watching
the -stable mailing list (and possibly even -cvs-all) and
reading /usr/src/UPDATING should be a "must". But there
are more things that can be done.
On important production machines, it might be a good idea
to track -stable with some delay. For example, always update
to the -stable date of 4 weeks ago (using the -D option of
cvs, or the "date=" keyword of cvsup), after making sure that
no critical problems have been reported in the mailing list
in the past 4 weeks. Chances are that critical bugs are
detected and fixed pretty quickly in the -stable branch.
And of course: Always make sure that you have good backups.
But that's even true if you don't track -stable.
PS: Some people think that a RAID1 (mirror) is a substitute
for a backup. It's not.
