So, how DO people upgrade > machines? The usual method is to cvsup sources and make world, build a new kernel and install it, merge /usr/src/etc as appropriate, and reboot. Apparently you don't have space to do this? If you want to do a binary upgrade, you can download the distributions to this machine (I'm not sure why your nfs mount here didn't work) and use the install.sh scripts. But the binary distro will overwrite /etc, which then needs to be reconfigured--hostname, nameservers, hosts, rc.conf, password files, the works. Backing up /etc and selectively reinstalling it files would be critical, before rebooting. You can also do a buildworld on another machine, and then download /usr/src and /usr/obj to this machine, and do a make installworld. That takes space but doesn't require the colo'd machine to do the build. You still have to merge /usr/src/etc and build a kernel. Actually the upgrade from 3.2 to 3.3 is not especially tricky.
