I've wondered about that, too, when working on the relevant section of
the Debian Live Manual.

Interesting approach.
As for me, I just never write to a USB key as root unless I'm absolutely
sure I need to. (Yes, I could still trash the wrong USB attached
storage, but that's likely less catastrophic than what I could
accomplish as the superuser.) What I wonder, though, is if it is
universally true that ordinary users will always have write access to a
USB key they've just inserted. Under what circumstances will they not?
Keep in mind, the user may very well be writing the USB from some
non-Debian system.
