I can appreciate the fact it's easier to follow one string for so many servers. > If you're just working with a handful of servers, -STABLE > would probably be fine, as long as you have backups and know > how to revert to previous versions when it becomes necessary. I do only have a handful of servers, however thousands of users, and indeed, I do have backups. The problem arises in a criticality that >20 minutes of downtime would lead to a severe problem....which brings up another good question...how do YOU revert back to a previous release? If you manage so many servers, I'd love to know what type of routine you'd use to revert back (and so would many others I'd think ;) Usually, as per my last message Re: Chad, the upgrades usually fail during one or two places: buildworld, or rebooting after installkernel. Both of those are easy to recover from. *knock on wood*, I've never had a showstopper after installworld before. I wouldn't know what to do if that happened. If installkernel reboots, then I've always been good after that.
