Changing hostname under OpenSUSE

One of the quirkiest feature of OpenSUSE is that, there seem to be no way to change or add hostname during the installation. For instance, I ended up with the hostname linux1-woj.

To change the hostname edit the /etc/HOSTNAME (yes, it's upper-caps) file and modify the hostname there. No reboot necessary, but GNOME or your UI might need so.
