First of all, the "os.setuid()" call is never reached. lgtm.com warns about that, and warnings are annoying because they require investigation. This code is only in the example, so that the user would understand that they should edit the source and set the desired UID. But you can only call setuid() if you have CAP_SETUID, so commonly this anyway doesn't work -- unless you are root already, and then you actually don't need it either. Let's drop this code from the example. Maybe this example really should be dropped. Does the "dbus" python module even still work? Doesn't for me...
