[Pdns-users] named view migration

[eli glynn]

Hi Frank, this is essentially identical to the problem I posed in the
"Overlay or pass-through support in PDNS?" thread from earlier this week.
Some way to avoid duplicate entries in "shadow zones", and instead have
PowerDNS perform the needed recursion if a record is not found in the local
authoritative zone (that is, an NXDOMAIN).

My digging so far leads to using a Lua `postresolve()` hook (or
`nxdomain()` + `nodata()` to achieve much the same thing).  I'm still
trying to get some working code implementing the recursion part though.

Thanks,
t.
