I have the following in my custom.lua:

  ["allow-recursion"] = "{ trusted; <my-kvm-host-ip>; }",
  ["also-notify"] = "{ <my-ns2-ip>; <my-ns2-ipv6; }"
I had to update the ns2 ip addresses, but now how do I force LC to rewrite named.conf.options? I tried restarting LC, then rewriting "DNS template" and "Extermal DNS Servers" but it did not change named.conf.options.

Shouldn't LC add the also-notify without resorting to custom.lua? Isn't it the idea that secondary DNS get notified?
