A partition that is totally off-limits unless I say otherwise is being mounted without my knowlege, permission, or directive AND I can't even unmount it?
Of course you cannot unmount your root partition.
That was a goof or maybe I was booted into partition 9-11, trying many different things these days. BUT your hint led me to question why KDiskFree was showing dm-9 as / when it was supposed to be partition 8. So I booted manually and got dm-8 which is what it should be. On the next boot I went again with the grub menu but ended up with dm-8 and not dm-9 as after the previous grub menu boot. I'll try to investigate a little more from a rescue frisby...
