Re: DHCP support

   Here is a patch to make pfinet use as IP address and make
   broadcasting possible when pfinet is started with `--dhcp'.
   Perhaps it would be nice to include this in the Hurd, or just in
   Debian if it is too much of a hack.  I don't want to put too much
   time in it if it is completely wrong.  In that case, just use it
   when you don't care about such things.

Indeed, it is a hack but it isn't really ugly.  But it would still be
nice to see it in the Hurd, and pfinet is a hack anyway.  Roland, what
do you think?

   Alfred promised me to make the dhcp client itself work.  I have
   some hacked stuff around to start with, the only thing that really
   needs to be done is hacking the script to change the ip address,
   etc, when the DHCP server replied.

Will do that when I'm in Uppsala.

Thanks Marco!

What if I use eth1 instead?
