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.
