Did you verify that dhcpd makes that arp entry? I had made that
assumption.

It's an interesting way of ensuring that if someone talks to your dhcpd,
they can only talk to your machine from that point on. Is this an
intentional security thing, I wonder.

Or is it due to the fact that somebody once had a building of diskless Sun
nodes and one day had 50 or 100 of them home to the wrong bootp server
(happened to me once ...)
