Or even better - right after networking comes up, start an iptables
script that is just the policies with DROP except for lo...
THen, after all other daemons come up, have another script that starts
your allows and such.

I guess I was assuming, since this server was running nfs, that it was
simply a host based firewall and that there was another firewall in
front of it, limiting that wee vulnerability. I can't think of a sane
reason to run nfs on a direct connect border firewall.
