[kubuntu] Changing the hostname -- I can do it but it's ugly

view story

http://ubuntuforums.org – I want to change the hostname of my computer. I can do it by editing (as root) the files /etc/hostname and /etc/hosts (unless I missed some other important place). But that's ugly. Is there a straightforward way to do it? (The hostname command only modifies your home directory.) This would be a useful addition to System Settings. (Hardware)
