fresh leap milestone 2.

I switched from the iso install source to the online oss repo. This repo had a
few differend packages compared to the iso. The gnome software installer
recognized them as updates. Once I had to shutdown the system it offered a knob
to install pending updates, then shutdown. I enabled that box, and hit return.
I think nothing was downloaded, but the box did a reboot instead of the
expected shutdown.

If that feature is not ready yet I suggest to hide it for the time being to
really and always do a reliable powerdown if that was requested.
