The DHCP client implementation on all Linux distros is sub-optimal, in
my experience. I'm involved in a rather slow-moving project to overhaul
Debian's Network config infrastructure, and this is one of the things we
will be looking at. I'm happy to receive any items for the "better
netconf wishlist". Best to send private mail, it's OT for this list.
