Comment 2 for bug 1742912

Please note that the simple test ( cat /proc/self/attr/current ) can be misleading.

I tried that in Ubuntu 18.04 ( switched to lightdm ) and got "(enforce)" but some applications like the file manager could browse other user's home directories. Most applications including firefox and libreoffice are restricted. In Xubuntu the file manager is restricted as well as every other application I tried.

Is it possible to just eliminate certain applications or prevent launching applications in specific ways to guarantee a restricted guest sessions?
