Re: no kickstart ?

I suspected wrong. The patch you mention may well break some things - I'd
set it back to 0 again... as you changed the hopcount, not the TTL for the
packets. The problem is the TTL being 0.

dhclient doesn't send packets with a TTL of 0, and it works. pump sends
packets w/ TTL=0 and they are discarded at the first router and never get
to the dhcp server at all.

Don't know what socket option(s) or ioctls pump is using that are
combining to result in discovery packets w/ TTL=0, but it is broken.
