Excellent answer Alexander.

(I'm back to scared again).

This will take some onsite research and testing.

My initial thought is to restrict Linux users to using a /linux folder 
on the drives; if not a flat-out separate partition (but that would be 
hard to make happen).


Thank you for the response!
