OpenSuSE 11, kdesu and sudo ;-)

Hardly more than a quick comment to daWuzzzz's last post:
Note that in 11.0 they switched from sudo to su behind kdesu. Starting YaST or KControl, you will still be prompted for the root password, even if you are a sudoer. Ben Kevan's blog has some recipe for that.
E.g. for KDE3, edit ~/.kde/share/config/kdesurc (or create that file).

[Passwords]
Keep=false

[super-user-command]
super-user-command=sudo

For KDE4, take the ~/.kde4/... equivalent (did it only on KDE3 myself). Of course, you can also switch kdesu to su on openSuSE 10.3 with the same method.
