OK, thanks for the screenshot (how do you do that during shutdown??? - it seems it isn't done by a photo camera)
(and me happy I'm not the only one with loop-things => if I know how you take a screenshot of it, I think I'm going to open a separate thread for that)
The problem is thus that /home don't get unmounted.....
=> don't know a solution at the moment, but I experienced it once [so thinking now about it]
