We thought of that too, but the question is, how does NFS handle
host name lookups?  I would assume it would do it when it tries to
mount the drive the first time, then use the IP from there on out,
otherwise it would be bombarding the DNS server with requests.
However, if there is a happy middle ground, say re-lookup every
hour or something, it would probably work pretty good to do it with
DNS.
