Hmm... That is what I expected it to do, but when I tried it, I ended up with an empty hostname. Of course, I don't remember now if I commented out that line or just set it to empty. Actually, looking at /etc/defaults/rc.conf I see that if I comment it out in /etc/rc.conf it gets set to the empty string in the default, so it shouldn't matter. Anyway, like I said, I tried that and just ended up with an empty hostname. Perhaps that indicates something is wrong with my configuration...
Thanks very much for the help (any other ideas?),

If you don't set your hostname in rc.conf, dhclient should change it
for you when it finds out what it is.
