New group for local users (WILL BREAK UPGRADES without manual intervention!)

Hi Ubuntu Sounders!

I just uploaded a new version of base-config that creates an
additional group 'plugdev' and puts the initially created user into
it. This group's purpose is to control access to removeable devices like
USB sticks and digital cameras.

I will upload a new version of libgphoto2-2 soon which will allow
access to USB digital cameras to plugdev members without any further
configuration. More importantly, I will upload new versions of
mount/umount and pmount/pumount which can _only_ be executed by
plugdev members.

If you install new Ubuntu versions from scratch, you will not have to
do anything. However, if you are upgrading from an older Warty, then
the already existing user(s) will not be put into plugdev
automatically, so you have to do this by hand:

# addgroup --system plugdev
# adduser <yourusername> plugdev

(as root). If you don't do this, you will not be able to mount devices
(as user) any more in the near future!

Thanks for your attention and have a nice day!

Martin
