That does exactly the same as the above adduser command.

And then wonder why the permissions are reset the next time he installs
an update for udev. :-) I just read
through /etc/udev/rules.d/40-permissions.rules and found this:

# IEEE1394 (firewire) devices
# Please note that raw1394 gives unrestricted, raw access to every single
# device on the bus and those devices may do anything as root on your system.
# Yes, I know it also happens to be the only way to rewind your video camera,
# but it's not going to be group "video", okay?
KERNEL=="raw1394",                      GROUP="disk"
KERNEL=="dv1394*",                      GROUP="video"
KERNEL=="video1394*",                   GROUP="video"

Sounds like you would just have to change this single line if you are
sure that you don't have any firewire disks.
