Be aware that with "zonefile-sync: -1" the journal will grow and grow
until it is full, as it doesn't only contain a simple diff/delta from
the original file (in git), but every single change applied - even
those changes that have been cancelled out by later changes (like old
DNSSEC signatures).

When the journal is full, you cannot submit further nsupdate changes
and I think DNSSEC re-signing is prevented from happening. Therefore,
as I understand it, "zonefile-sync: -1" is not suited for production
