Unfortunately, to get newer versions and hopefully out of Nvidia kernel
update hell, I went from LTS to the next regular unsupported, hoping to go
beyond that one to contemporary, but all went astray into unstable and
unbootable, probably in the filing to upgrade multiple times, repository
problems and bugs in same...

Possibly waiting a bit on 15.10alpha to mature and upgrade nonbootable disk
from cdr/dvdr/usbstick/netboot to get back to a working system.

Waiting for godot was too frustrating.
