One can change the database reference in named.conf to do this.  The
difference is that db.root references 'the' root servers.  You can
choose which ones you want to use in the zone file:

  // prime the server with knowledge of the root servers
  zone "." {
          type hint;
          file "/etc/bind/db.alternative_root";
  };

The trouble with removing db.root is that it may not be obvious how to
recover when it is missing.
