Unfortunately it's not that black and white, root can do some evil stuff
with the mem/kmem, drm/xf86 and a boat loat of other gateways into
kernel land.
The point is that root can do a lot of stupid things, this is a feature,
not a bug.. abuse wisely.
In this case the kernel was told, by root, to interpret garbage on some
partition.. pleasing 'root' is a high priority to 'kernel', they have a
friends with benefits relationship.
It's the best peep show I've seen, excluding all the ones with boobs.
Enjoy Unix, I sure do.
