Comment 7 for bug 885027

You mean that a program designed to let an unprivileged user
mount/unmount/eject anything he wants has a security flaw because it allows
him to mount/unmount/eject anything he wants? I'm shocked.

Implement a system that allows an appilcation to mount/unmount/eject USB
devices connected to the system securely, then make sure that system is
universally adopted on every linux install in the universe. Once you've done that, feel free to
re-open this ticket.
