nsupdate doesn't edit any files, right?

Well, we're not trying to parse disk files.  The main
issue was that we want the changes to be persistent in
some way, otherwise it's kind of pointless, no?  We've
got web hosting appliance software (Ensim Webppliance)
that will let our customers order and create their own
virtual hosting site on the fly.

For this to be as hands-off as possible, we want to
automate the new DNS entries as the new sites are
created.  We have dedicated DNS servers and don't want
or need the appliances to do DNS.

Actually, does nsupdate allow you to add entire new
zones too, or do the zones have to exist on that DNS
server already?

Thanks!
