  Hash : 5effc14a
  Message : Reenable "val-log-level: 2", so that when sites have misconfigured dnssec the sysadmin has some idea what's going on in logs, and "aggressive-nsec: yes", if we're using dnssec anyway we might as well get the benefits. These were both enabled last time dnssec was enabled in this sample unbound.conf. ok florian@
