I've been using noatime for some months on /usr with no apparent ill
effects.  Running Apache 1.x, Named, Dovecot, Squid, Samba, Fetchmail &
Sendmail, among other things.

I don't use noatime on the other mounts.  I seem to vaguely recall it
causing some things to break.  It may have been something like tail -F
/var/log/messages not working the way it should, but don't quote me on
that.
