Can we update the DNS dynamically [1]?  Can you share the script?

I still don't know as much about Knot as I should, but I'm surprised
that a change to the primary server's database would not be propagated
to the secondary server's database automatically.  Can you elaborate on
what goes wrong, or maybe explain (even at a high level) how I can try
reproducing the problem with cert renewal locally?
