Comment:

 Copying from the devel thread
 (http://lists.laptop.org/pipermail/devel/2008-September/019135.html):
 {{{
 The XO currently sets the group for /dev/ttyUSB0 to 'uucp'.
 So, my proposal is that (a) the 'olpc' user be added to the 'uucp'
 group, and (b) that the permissions.info file may be used to request
 that the activity's "isolated" UID also be a member of the uucp group.
  (See
 http://wiki.laptop.org/go/Activity_bundles#activity.2Fpermissions.info
 for Michael's documentation of the permissions.info file).

 Does this seem right to you, Michael?  I think rainbow already has a
 mechanism to create local copies of /dev/video etc for access to the
 camera, etc; perhaps he'd prefer to use that mechanism instead.  (I
 personally like trying to use the traditional groups for their
 intended purposes whenever possible, to avoid surprises.)
