Hi Mark!
Do you know when BIND 9.3 will be available?
I also would like to know if the following features are going to be supported in BIND 9.3:
True Round Robin (not only random-cyclic as in BIND 9.1.3)?
Support to turn on debug from the rndc program (not yet implemented in BIND 9.1.3)?
BR,
Johan Larsson

You will need BIND 9.3 to get this fix.
1224. [bug] 'rrset-order' and 'sortlist' should be additive
not exclusive.

There is no default sortlist.
