I have set up a Bind-9.11 service (inside a jail).  In doing so I
noted that the default named.conf file provided contains no less than
161 pre-defined zones that all point to:


These zones are prefaced with the following statement:

/*	Serving the following zones locally will prevent any queries
	for these zones leaving your network and going to the root
	name servers.  This has two significant advantages:
	1. Faster local resolution for your users
	2. No spurious traffic will be sent from your network to the roots

So, what happened to the 'empty-zones-enable' and 'disable-empty-zone'
options?  Why are these zones explicitly defined?
