You can't handle permissions that slipshod if it's for a repository used by several "Sub-"Ubuntus. Note that I installed Edubuntu and then added the Ubuntu Studio repository. Now imagine that this Edubuntu is used by very young children (btw. it isn't used by children on my machine). It's better the admin needs to google for an issue such as a group audio, than automatically add users to groups. If you want your children being able to run http://www.tuxpaint.org, you might not want them to be able to run your audio work to sync a raunchy video too ;). This of cause isn't a good example, since we would disable permissions to open such a project folder, because a group audio anyway wouldn't protect against access. As long as your Linux is for a single user only and it e.g. might only be a DAW, perhaps without an Internet connection, you can set SUID for all folders, you can run audio sessions as root etc., but as soon as it's a multi-user machine, there's the need to have an admin with knowledge. Regarding to the group audio there might be no security issue, dunno, I just want to warn that there might be a risk we all miss. 2 Cents, Ralf -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
