4880.	[bug]		Named wasn't returning the target of a cross-zone
			CNAME between two served zones when recursion was
			desired and available (RD=1, RA=1). (When this is
			not the case, the CNAME target is deliberately
			withheld to prevent accidental cache poisoning.)

			This can be overridden by specifying another

			however, for functions requiring full cryptographic
			strength, such as DNSSEC key generation, this
			cannot be overridden. In particular, the -r
			command line option no longer has any effect on
