I think I figured out what he's doing and I'm kind of surprised that
it works at all. He's expecting the system to use its IP address to
lookup its hostname. That seems wrong. Maybe what is working is
that the installer does that lookup and sets the hostname during the
install. But that setting has become transient for some reason (which
I think I've noticed, but didn't investigate). The DCHP server is
the one that's supposed to be supplying the hostname.
I don't see why that's wrong, there were plenty of things that discover
their hostname by doing a reverse look-up of their IP. And he
demonstrated several releases that worked exactly that way.
What are these plenty of things? This is the first that I know of. And
the question still remains. Is the OS looking up the hostname at
runtime or was it always the installer setting it at install time?
