So what happens if I insert a USB key containing a device node to the
hard disk ? Why is this functionality useful in the current form ?

(ie I think you need an actual rational security model first)


Also why is this at the per fs level duplicating stuff each time rather
than at the vfs level - this seems to be vfs level functionality.
