        Have you actually tried to sign a zone?
        Have you actually tried to re-sign a zone?

        Just use the defaults and don't try to control every aspect.

        It really is not that difficult and yes it is getting easier
        still.  If you can manage a zone, you can manage a signed
        zone.

        If you are writing a nameserver there is a lot you need to
        know but to administer a signed zone there is very little
        you need to know.
