zone transfer for zone "localhost"

[Jeff Stevens]

I have a customer complaining this zone transfer always fails with an "up to
date" error, and I think they are under the impression they can actually
share such special zones with slaves.  I've been trying to find a
description of a restriction for "localhost" zones...anyone know the
official answer to this?  The 192 isn't routable...so I don't know what 
they're really doing with this zone....

The customer has it configured this way:

master named.conf:
------------------
zone		 "localhost" {
		 type master;
		 file "LOCALHOST.DB";
		 forward first;
		 check-names ignore;
		 dialup no;
		 notify yes;
};

slave named.conf:
-----------------
zone	"localhost" {
	type slave;
	file "LOCALHOST.DB";
	masters {
		192.168.2.10;
	};
	forward first;
	check-names ignore;
	dialup no;
	max-transfer-time-in 60;
	notify yes;
};
