I think "well defined" is stretching it anyway. I see different
behaviors (partially or fully qualified hostname) on my different Unix
machines. --fqdn appears particularly useless, as Fedora 10 reports
this:
$ hostname --fqdn
localhost.localdomain
and my other machines don't recognize the switch at all.
