Remove obsolete fax, tape, scanner privilege groups

In Ubuntu 8.04 final it is the {fax, tape, scanner} groups that are missing. fuse is included now.

These groups should not be added in gnome-system-tools rather. We do not use fax and tape at all, and scanner is deprecated since Hardy (replaced with dynamic ACLs).

I disagree. The administrative user should have all rights by default. By definition.

In a few cases this could even be essential, so there's practical relevance as well.

In Intrepid and Jaunty, the user defined during installation is not member of the "video" group. Would you like a separate bug filed for this?

The "video" group is used for /dev/dri/card0 and avoids chmod 666 on it.

Jaunty:
$ id tormod
uid=1000(tormod) gid=1000(tormod) groups=1000(tormod),4(adm),20(dialout),24(cdrom),46(plugdev),108(lpadmin),122(admin),123(sambashare)

Also "audio" is missing, which is used for /dev/audio and /dev/snd/*

What is maybe confusing here, is that the obsolete groups show up in gnome-system-tools at all.

Martin Pitt: users-admin lists the privilege groups that are present on the system. If they are not created, they stay hidden. So I'd say there's a bug in Ubuntu, with some packages creating those unused groups.

This is still untidy and confusing in Karmic. gnome-system-tools still lists a long list of privileges. For instance "Connect to wireless and ethernet networks" is not even selected for a new Administrator. So it is probably not in use (it works fine without) and should not be listed. If we can not delete these groups (from base-passwd?), we should patch gnome-system-tools to ignore them.

I think your statement is flawed by the assumption that we cannot remove those groups. They should at least not be created, and when upgrading, update-manager could remove them, especially if they are empty. Leaving them on the system is confusing anyway, even if it's to a lesser extent.

As I said, that's not primarily a users-admin problem for me. Anyway, in Lucid we now hide the detailed privileges in an Advanced dialog.
