Of course the smart thing for me to do would have been to setup my
faiserver (at home) as an ftp server so the faiclient could grab
base?_?.tgz from there.

The problem was showing up in make-fai-nfsroot at: 
    chroot $NFSROOT apt-get update
	inside the $NFSROOT would exist $NFSROOT/etc/resolv.conf ->
/tmp/resolv.conf, but during the run of make-fai-nfsroot there isn't
anything in /tmp/resolv.conf, so the chroot'd process has no idea which
nameservers to use.
