Thats definatly true. Ideally I dont believe in upgrades, so a fresh install,
fresh rebuild of everything, and fresh redeploy of everything is the best way
to go. Im willing to do this under extreme duress (i.e. its all broken) but
since I've hot-upgraded same major releases of FreeBSD dozens of times, and
its never once failed.. Well, its worth the risk to me to save all that time.
It is odd that his 2.2.5 system is behaving badly, when others seem to be
going well. Perhaps its NFS related?
