Are you using privsep? If so, I think this is expected. The unpriviliged
side runs in a chroot under /var/empty. This means, that it cannot see any
/etc/nsswitch.conf and cannot see any /etc/resolv.conf or /etc/hosts.
And the resolver client library defaults querying on the first interface,
and in your case it used localhost.
