Yeah, this actually happened two days ago...

I lost /root and /usr. Luckily and just by accident I had a backup of /usr, but not /usr/lib (living on another disk). I can use my machine, the libs seem to be still good enough for KDE, but e.g. my gcc fails miserably. So I'll have to bootstrap my system from scratch... :(

Well, at least I can work currently, the bootstrapping will have to wait until next week, too much to do this week and I'll make a complete cleanup-action out of this. I already reorganized the mounting of the harddisks in the case and the next step will be cleaning the bits and bytes. I have a couple of dozen gigs trash lying around...
