Are file permissions in files on external devices silly?

It doesn't have to. Ubuntu knows which devices are removable. Having
user and group ids enforced on them is silly, because these devices
are supposed to be switched between machines, which means that any
machine with root access can break this "security" feature.

It can be solved by simply not enforcing user and group ids on
removable devices.
