What we do is build one, then create /boot/new and /new on the next server, rsync over to them, then mkdir /boot/old and /old, and (using zsh with modules loaded) mv * old, mv old/lost+found ., mv old/new/* ., make sure a few things are correct (for example, ifcfg-eth*, /etc/ssh/), and sync, then reboot. All your other stuff is fine.... mark
