Please, PLEASE, reconsider.
I've long hated this thing of assigning the hostname to 127.0.0.1, it
always breaks when using kerberos/winbindd as the hostname needs to
reflect the public facing ip.

I personally think that Gnome is at fault here, is there any smarter way
to at least change the hostname mappingi hosts when the main network
interface gets an IP?

Simo.
