I was reading unbound.conf(5) because there is no relevant doc in the Guides
section. I'd say, a separate "HowTo Configure Forward For Local Zones" document
would be ideal for my particular case. Or, spray hints in the unbound.conf
manpage like so:

- In the description of "forward-zone" and "stub-zone" mention that:
 + if this is a local zone that does not have a DS in the parent zone, you must
list the name as "domain-insecure",
 + if it may contain private addresses, then also in "private-domain"
 + if it is a reverse zone for private address range, the zone needs to be
configured "local-zone: <zone.in-addr-arpa> nodefault"
- In the description of "forward-addr" note that if you specify loopback address
you should also add "do-not-query-localhost: no"

I think a separate HowTo might be better because this is a relatively common
setup, so many would benefit, and on the other hand the manpage is rather long
and dense already. I could knock up a short doc, shall I try?

Regards,

Eugene
