Usually you can buildworld on one production machine in advance and then schedule downtime for when you want to installworld. Then we usually use rdist or rsync to do keep the rest of our production machines in sync with this master machine. This procedure has worked quite well for us since 2.something. It also has the advantage that if something goes pear shaped during the upgrade, you have other machines with exact copies of all the binaries so you can restore the machine back to it's old state without resorting to tape.
