Putting it in the subnet is fine. In fact, I recommend it, since the host
will inherit options from the subnet level. That warning just means that the host
would be assigned that IP regardless of which subnet it is on.

Yeah, I've seen this before. Some linux distros ship with a dhcpd.conf file
that is incomplete :( It seems silly to me ...
