[erlang-questions] Broken ipv6 behavior?

[Matthew Dempsky]

Okay, so now that breaks looking up localhost:

matthew@REDACTED:/tmp$ erl -kernel inetrc '"/tmp/inetrc"'
Erlang (BEAM) emulator version 5.6.1 [source] [smp:2]
[async-threads:0] [kernel-poll:false]

Eshell V5.6.1  (abort with ^G)
1> inet_db:set_lookup([dns]).
ok
2> inet_db:add_ns({10,0,1,40}).
ok
3> inet:getaddr("ipv6.google.com", inet6).
{ok,{8193,18528,0,4097,0,0,0,104}}
4> inet:getaddr("localhost", inet).
{error,nxdomain}
5> inet:getaddr("localhost", inet6).
{error,nxdomain}

Looking at my DNS cache logs, Erlang is now sending queries for
localhost.local.

If I change [dns] to [files, dns], and it gives the same wrong output.
(I also tried adding "9.9.9.9 localhost.local" to /etc/hosts, and it
still gives nxdomain.)
