I thought it was checking for the problems that might have happened on the
flag day, but in addition it was checking for all sorts of other potential
problems, and giving unclear messages about them in addition. It appears
that if you have a recent FreeBSD, the flag day is of no concern.
There are only a handful of DNS servers in wide distribution - odd that
there is no list of compliant versions anywhere on the web.
