Stop DHCP screwing up your Mac OS X hostname

I'v got Snow Leopard, but DHCP is screwing my hostname all the time to something very random. Another thing that /etc/hostconfig goes away, while System Preferences in the Sharing tab does not sets hostname as hostname. Thus all older recipes are not really applicable anymore, once you're on Snow Leopard (I love changes). The cure is how to setup your hostname to, e.g. "Zeus" (that's mine one) like this (terminal and sudo privileges are required):
sudo scutil --set ComputerName zeus
sudo scutil --set HostName zeus
sudo scutil --set LocalHostName zeus
That's it (no reboot really required).
