Do you have a tracking/reference number for me?

So are you saying that even if the bug is fixed, bind does not support:

options {
 	dnssec-enable yes;
 	dnssec-validation no;

If so, should those options not be merged into one option? Or should
named-checkconf return a failure for such a configuration?

Does anyone know how prevalent these configurations are?

I'm CC:ing the dnssec-trigger list, as it might need to come up with a
new probe to detect this.
