It's not robust to use resolv.conf in this way at all. I don't use
"domain" directives in that file on any of my hosts, since the "search"
directive conflicts the "domain" directive (and I use the "search"
directive).

You might be able to rely on "domain" being in resolv.conf on each of
your hosts, though, so this could work at your site. Just be aware that
it's no guaranteed to work on all hosts.
