DHCP 4.2.3-P2 doesn't remove TXT and PTR records but only A records when leases are released or expired.

[crocket]

When dhcpd receives DHCPRELEASE for a client, it expires the lease for
the client and removes only A record of the client but ignores PTR and
TXT records.
When a lease expires naturally without a DHCPRELEASE message, every
resource record regarding the client is discarded.

I think it is a bug.
