BIND-9.11 --enable-empty-zones

[James B. Byrne]

The default /usr/loca/namedb/named.conf file shipped with the FreeBSD
BIND packages has numerous 'empty' zones configured such as:

// Private Use Networks (RFCs 1918, 5735 and 6303)
zone "10.in-addr.arpa"{
  type master; file "/usr/local/etc/namedb/master/empty.db"; };
. . .

It also contains these statements:

// These zones are already covered by the empty zones listed below.
// If you remove the related empty zones below, comment these lines out.
	disable-empty-zone "255.255.255.255.IN-ADDR.ARPA";
	disable-empty-zone
"0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.ARPA";
	disable-empty-zone
"1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.ARPA";


My question is why does the default file not simply use:

 --enable-empty-zones yes;

and eliminate an awful lot of verbage?
