Here's a patch to use a separate RuntimeDirectory. Seems to solve my issue (so far).

Additionally, both isc-dhcp-server & isc-dhcp-server6 service unit files specify the RuntimeDirectory 'dhcp-server', which is removed when either unit stops (and thus would wipe out the other unit's pid file, were it being successfully written).
