Re: [knot-dns-users] migrating from bind to knot

Hi MJ, If you're using the same Knot instance to host a mix of primary (signed) and secondary zones, then I suggest you set "zonefile-load" to "none" in your template, and then override it with "difference-no-serial" for the primary zones. Secondary zones don't need a zone file at all. Incoming XFRs are stored into the journal, and the zones are loaded entirely from the journal at startup.
