Better correct myself here. POSIX provides a way for apps to query the
canonical host name, but DOES NOT REQUIRE IT TO BE A FQDN.
So, it provided the notion of a "special name", the canonical host name.
In practice, it has to be a FQDN, but that's due to bad usage by
applications, not a POSIX (or SuSv3) requirement.
And anything that depends on it to be unique in the whole world is broken.
