devices that provide storage interfaces are likely to be the next
barrier, and so all we have done is accept the non-storage devices now
and create more pain later.

what is the reason for not allowing user-level read/write access to any
storage USB device?

i recall setuid used to be a risk, but i thought that got fixed with
mount options that suppress it.
