Yes I am well aware of that, we are going to implement the same stuff in
cifs.ko, ie you have to authenticate to get access. Still it make me
question if I want to give a sudoed app access to my material, if I
su/sudo to root then probably it's ok, root is powerful enough to be
trust-able by a mortal user. If you su to another user, things change a
lot IMO.
