Brad,

I think you are misunderstanding me. I understood that you wanted to
use DHCP for the machine you are using as an NFS server and I
suggested having the DHCP server assign your NFS server a fixed
address based on its MAC.

In dhcp.conf you would have something like the following to do that ...

host nfs-1 {
  hardware ethernet XX:XX:XX:XX:XX:XX;
  fixed-address YYY.YYY.YYY.YYY;
}

where XX:XX:XX:XX:XX:XX is the MAC address of your NFS server and
YYY.YYY.YYY.YYY is the IP you want to always assign to it.

You can then have your DNS server get updates from your DHCP server or
you can just set up your DNS server to resolve the name and IP
correctly.

Either way, if you aren't running your own DNS and DHCP servers, then
perhaps this isn't what you really want to do.

I think you are going to just have problems if the IP of your NFS
server keeps changing. I don't know how to configure /etc/fstab to
accommodate that. It expects an IP or a name that resolves to the
correct IP. But you can configure DHCP to not change the IP of your
NFS server. That is what I was suggesting.
