This looks clever, but many people use the actual client identifier - even if only to stop idle RAS allocations from consuming their pools.

This is from the dhcp-options man page:
option dhcp-client-identifier string;
This option can be used to specify a DHCP client identif-
ier in a host declaration, so that dhcpd can find the host
record by matching against the client identifier.
I haven't tried this, but what about setting it, eg:
option dhcp-client-identifier hardware;
Maybe try it and see?
