	Why would one want to use $GENERATE. 

	zone "127.IN-ADDR.ARPA" {
	};

	@ SOA ..
	@ NS ..
	1.0.0 PTR localhost.

	No.  It's the name of the primary (only) nameserver.  It just
	happens to be the name of the zone as well.  The zone names
	are all legal hostnames.

	draft-ietf-dnsop-default-local-zones-02.txt

	There are also named.conf options to change what is returned.
