BTW, I should have stated that the patch I just sent is for Erlang R8B
and NetBSD-1.5.2, tested and in use.

We have been using the ets:insert(inet_db,...) workaround on our
OpenBSD Erlang nodes for over a year.

NetBSD docs state that the resolver defaults to "hosts files dns" in
absence of an nsswitch.conf file or hosts entry in that file.

[ferrets about in sources]

I see what you mean. Erlang seems to use its own resolver,
inet_dns.erl, as opposed to the one in libc. Mostly.

Nice. Will test it asap. Will help with OpenBSD too, no?
