Ambiguous def of multiple CNAME

[Christine.Tran at east.sun.com]

The bind config file guide -- options statement says:

multiple-cnames
	If yes, then multiple CNAME resource records will be allowed for a
	domain name.  The default is no. <snip>

Which is forbidden, this(1):

oak	IN	CNAME	tree.foo.com.
birch	IN	CNAME	tree.foo.com.

or this(2):

oak	IN	CNAME	tree1.foo.com.
oak	IN	CNAME	tree2.foo.com.

or this(3):

tree	IN	A	1.2.3.4
tree	IN	A	5.6.7.8
oak	IN	CNAME	tree.foo.com.

(2) and (3) tries to achieve the same effect.


Say I am auth for foo.com and not auth for blat.com.  Can I do:

server.foo.com.	IN	CNAME	server.blat.com.
I am almost sure it's not kosher, but so far it's worked.  I'm on BIND8.2p1.
