Thanks, but I think there are easier (aka better) ways.  for instance, if I 
switch dhclient to dhcpcd, I can put -h $(/bin/hostname) somewhere.  I was 
trying to stay as close to the default Ubuntu install so that I could suggest it 
being added to dapper++.  given that Ubuntu uses dhclient out of the box, and 
dhclient will support sending the Box's hostname "soon", I am content editing my 
config files and waiting for dhclient before I suggest any Ubuntu enhancements.

Thanks again for your interest.
