hostname and dhcp

[Evan Dower]

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?),
