Default unbound reverse lookup private zone

I am using unbound on my local network. Direct lookup works without hitch. Also
when I do something like

Code:
$ dig @localhost -x 127.0.0.1 +short
I get

Code:
localhost.

I am completely confused if it would be possible that I get reverse lookup for machines on my local network by somehow configuring unbound.conf file?
For example

Code:
$ dig @localhost -x 10.0.0.1 +short
fileserver.oko.net.
Reading through documentation I see

Code:
server:
	local-zone: "10.in-addr.arpa." nodefault
stub-zone:
	name: "10.in-addr.arpa."
	stub-addr: ip-of-your-private-dns-server
Which looks like I need to run NSD and replace its address instead of ip-of-your-private-dns-server to get reverse lookup. Is that correct? I am also a bit confused about nsd.db? It looks like this thing is created at least on 3.2.26 by compiling data from zonefile. Are zonefiles identical to BIND zone files?

I am going to answer my own question . No NSD is not necessary. To have a reverse lookup enabled on the local network one can hardcode ptr data for local machines as

Code:
 local-data-ptr: "10.0.0.1 fileserver.oko.net"
Enjoy!

Yeah unbound isn't a very powerful authoritative DNS server (it wasn't intended to be, afterall), but it does have some "hardcoding" capabilities that make it functional for small installations to not need something like BIND or NSD. I love the stub-addr capabilities, though =)
