One other big difference between bootpd and dhcpd right now is that
bootpd uses a different mechanism for unicasting to the client -
rather than using BPF, it stuffs an entry into the ARP cache.   Some
old, buggy boot proms don't respond to ARPs, so they can't TFTP with
dhcpd, but can with bootpd.   You can work around this by manually
stuffing the ARP cache, but it's kind of evil.   People have made
noises about contributing code to fix this, but nobody's done it yet.
