Should I create a group jazip

[Peter S Galbraith <GalbraithP@dfo-mpo.gc.ca>]

My jazip package is almost ready to be uploaded (X tool to easily
mount and unmount Iomega Zip and/or Jaz drives), but there's a
final detail.  It is suid-root and gives all users the ability to
mount and umount zip and jaz devices.  I explain why it is
suid-root in README.Debian and also say how sysadmins can opt to
control user access by creating a jazip group.

Here's the text relating to this issue in README.Debian of the
unreleased package:

-------------------------------------------------------------------

 jazip is suid-root.  Once this package is installed, _all_ users on the
 system will be able to mount and umount Zip and Jaz disks (Disks are
 mounted with the nosuid flag to increase security).

 Why is jazip suid-root? 

  jazip uses SCSI_IOCTL_SEND_COMMAND ioctl to send commands out to the
  SCSI host.  The kernel requires root privileges in order to do this 
  (see /usr/src/linux/drivers/scsi/scsi_ioctl.c).

 How can I control users access to jazip?

  One way to do it is to change permission and group ownership of the jazip
  executable like so:

   $ ls -l /usr/bin/jazip 
   -rwsr-xr--   1 root     jazip      147340 May 18 15:04 /usr/bin/jazip

  Then only members of group jazip can access the suid-root jazip
  binary (Use the add-group command to create the jazip group and the
  add-user comamnd to add users to the jazip group).

-------------------------------------------------------------------

The question is:

 Do I leave this as it is,
 or do I create the jazip group in the package installation?

Policy says that I should create a Dynamically allocated system
group (range 100-999) using adduser --system after checking with
the base system maintainer (that would be base-passwd?) and
debian-devel.

If I do this, I don't really need the user ID, but only the group.
Can I use addgroup instead?

As usual, thanks!
