Hmmm..... interesting. "Games" rang a bell so I just took a look at my group file and there is games group, number 20 on the list, but I didn't add it.

My understanding of 'games' was that it is intend to be used by SGID executables and not added to individual users. The idea being that it stops users cheating by manually editing game files that contain things like high-score tables or saved game states. I don't think slackware actually uses SGID 'games' on the bsd-games collection, but if I remember rightly OpenBSD implements it that way.

Not all groups are intended for use by users directly.


On the subject of users/groups. OpenBSD recently started using user and group names starting with an '_' (underscore) for the various daemons and other system components in order to distinguish them from general users and groups. IMO it's a very good idea.

Not sure how many Slackers do it, but it's a quite common approach and is the default approach on a number of linux distro, and indeed some of the proprietary UNIX also.

groupname=username, gid=uid is the way I normally do my users.

Thanks for all your answers. I did have issues with k3b as well, which was one of the intentions to post this question. After adding my user to all suggested groups the issues were still present and the error messages still suggested a problem with permissions.

However, I am using cdrkit now instead of cdrtools. cdrkit is a fork of cdrtools created by Debian developers in 2006. With cdrkit and k3b burning optical media works just fine.

Didn't know about this change in BSD, but I agree, it's not a bad thing to have visual "tags" for usage/policies, we do this a lot in programming.

On the "games" group: One SlackBuilds.org package that needs to be run by user accounts in the "games" group is nethack. I am no longer maintaining that, but I can put you in contact with the current maintainer if you'd like.

In order to bring up the bluetooth configuration GUI in KDE, I needed to be a member of the messagebus group.
