Ah, now I see. I missed that PDNS was adding the "." to the SOA record
when setup as a slave. It has been doing that for a long time and we
have never had a problem. I would just not add the "." when adding
records manually to the DB, although it looks like a "." at the end
of the primary NS delegation in the SOA record is okay.
