Bind query logging

Hi Zoltan,

I don't see the "default" category defined there.  The default is
syslog I believe.  This might be why you are getting some logs in
syslog: see: https://bind9.readthedocs.io/en/v9_18_11/reference.html#logging-block-definition-and-usage
for further info.

Perhaps define category default { } and a channel { } to go with it?

I have this in my server:

  channel primary_log {
    file "/var/log/named/primary.log" versions 10 size 10m;
    severity info;
    print-time local;
    print-category yes;
    print-severity yes;
  };
  category default {
    primary_log;
  };

Thank you,

Darren Ankney
