IPv6 logging noise

[Philip Prindeville]

Hi,

I’m on a US residential ISP, and they don’t support IPv6.  As a result, I’ve disabled it locally as well with `options { listen-on-ipv6 { none; }; };`.  Well, there are more options than that, but that’s the relevant one.

If I run with `-4` then the noise goes away.

I was wondering if:

(1) that `listen-on-ipv6 { none;}` should imply `-4` (the simplest) or

(2) that there’s an easy way to parse and dump the options so my startup script can see if this option is set or not, and if it, add `-4` to the arguments it uses to start up named.

I ask the second question because of the format of the config file, newlines and spaces are arbitrary so there’s no single canonical format I can search for.

Thanks,
