Aarrghh! You're absolutely right. I read the BSD manpage for hostname.. 
I can understand why BSD and Ubuntu behave differently, but then why
does Gentoo behave the right way (the BSD way)? I don't have access to
the Gentoo box atm, but I'm quite sure hosts looks something like this:

127.0.0.1       localhost.localdomain localhost
192.168.1.120	my.host.name my

In that case, the gentoo box should respond to hostname -s with
localhost. But I know that it gives me 'my'..

Anyways, that's a minor issue. I'll figure that out when I have access
to my box.
