The single user mode issue(I think) was meant for those slow machines without enough processing power, because then the server services are not running. With fast boxes I think that step is unnecessary. I do upgrades here while the servers are running (http, Proxy, POP, SMTP, radius...name them) and my only concern ever has been when I have to reboot so that I have a kernel in sync with userland. That is normally after the mergemaster stuff - but I always do it because it takes me 5 minutes MAX to reboot. What I do: cvsup make world (I don't split it into buildworld/installworld) make kernel mergemaster reboot I think the only concern would be if the box failed to boot back into server mode because of a little error but you can have some dumb guy at the other end help you do things by you shouting commands on the phone. I've never been that unlucky though. The tricky part is mergemaster. PS: I stand corrected though. -Wash -- Odhiambo Washington Wananchi Online Ltd., wash@wananchi.com 1st Flr Loita Hse.
