Awesome! I included your patch in the Debian Hurd package.

What about that --dhcp option?  Not a big deal (I'll remove it from
dhcp-client), but will it break for current users when they install the
new pfinet?

One nitpick at the diff you sent: don't include the ChangeLog in the
diff, include it detached in the mail body (otherwise, applying the diff
later will fail if the ChangeLog got written to in the meantime)
