Re: 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?),

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