Why does named log an error 'disabling RFC 1918 empty zones' when starting up?

In obsolete versions of BIND, named could log this message at startup:

Warning: 'empty-zones-enable/disable-empty-zone' not set:
disabling RFC 1918 empty zones

This behavior was eliminated in BIND 9.9.0.  All branches that contained this log message have passed end of life; if you encounter this message, you should upgrade.

    [ Ulrik]: 9.9 behaviour 2013-02-01 16:36

    I realise this page is not mainly about Bind 9.9 but a link to the appropriate manual describing Bind 9.9 behaviour would be helpful for those of us sent here via Google.

    Hi Ulrik,

    I have updated the previously-broken documentation link to point to an overview page that covers all versions, including 9.9.

    The best place, however, to read about the behavior of 9.9 is the "Automatic empty zones (including RFC 1918 prefixes)" article mentioned above.
