By definition, FCrDNS uses DNS lookups. Unless you're using dnsmasq,
the entries in /etc/hosts are ignored during DNS lookups. Unless I'm
mistaken, no FCrDNS implementation ever queries /etc/hosts (nor should
it). This means FCrDNS will conclude that localhost does not resolve
and that 127.0.0.1 has no rDNS (excepting cases where the admins have
manually placed such entries into the local DNS).
Okay, I'll buy that. I guess I usually think in terms of gethostbyname()
and related functions, rather than a pure DNS query.
Apologies.
