I used rsync (and a ruleset) to "clone" an old box to a new box (both FreeBSD 4.4). I maintain exact copies of /etc/* and /usr/local/* on several other servers by croning rsync, too. Interestingly enough, while at first I did this on boxen that were identical hardware (Dell Poweredge 2500's), I subsequently rsynced folders on different hardware (Poweredge 1300, 1400, 1400SC, and an Optiplex, just for good measure) and I had zero erros or inconsistencies among these boxes. I also heavily use Webmin for the "little" stuff for maintaing our server forest. I does exactly what I need it to do.
