When I did a 2.2.8-STABLE to 4.3-STABLE upgrade, I ended having to do it in one broken-up step. First (and the only sane way, IMO) is to do the buildworld on a 4.x system; get all those lib conflicts and crap out of the picture. Then I installed the 4.x kernel, did the necessary frobbing (installing loader, re-disklabel -B'ing, sd->da renames in /var with mknod, etc), booted up the 4.x kernel, THEN did the installworld, mergemaster, reboot. Some issues I found: - Some apps (portmap in particular) caused no end of trouble when the 2.2 app ran under the 4 kernel. Like, kernel-panic type trouble. - Device renamings are a bitch. In theory, a 3->4 upgrade should be easier than this, since you don't I think need to do any device renaming, which solves a bunch of my problems right off. I'd still be pretty leery about doing it remotely, though. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Unix Systems Administrator | fullermd@futuresouth.com Specializing in FreeBSD | http://www.over-yonder.net/ "The only reason I'm burning my candle at both ends, is because I haven't figured out how to light the middle yet" To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
