Bug#788662: Logged-in user no longer granted permission to removable disks

Hey Josh,

That's expected. As Michael already said, we never explicitly granted
user access to device nodes. Maybe in the past some devices got that
through specific group membership, or you had some custom udev rules
to do that; but throughout the history of pmount, hal, consolekit,
udev etc. in Debian the device nodes themselves weren't user
accessible in general. The main exception there that I remember is
Fedora's/Red Hat's ancient console_helper (or something similar) which
actually changed the device nodes themselves. But that was some decade
ago already..
