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?
