You can seemingly run uname -a from a terminal app I downloaded called mg-Terminal. The only repositories I have added are to MeeCatalog, is that what you are talking about? I guess MeeCatalog is separate to the "main" repositories? Even then, I only went ahead and ticked the ones that were already present in MeeCatalog's settings menu, not added any manually. I don't believe I have root access as running devel-su outputs "not found".
