well, for your nearby environment, you can always have a /etc/hosts, and
specify file,bind in /etc/resolv.conf. And it doesn't hang, it just time
out slowly :-) Btw, some tcsh version have a bug which requires DNS just
to start up, but this is tcsh's fault, not the systems.

hm...

ln -s `which amd` /etc/rc.d/1/.

instead of editing rc.local? Might be an idea.
