I have similar question concerning the cssu-testing and cssu-thumb: If I have installed cssu-thumb, should I keep cssu-testing disabled? My reasoning is that does the cssu-thumb contain all the same libraries,sw etc than cssu-testing, or only those that have been thumb-compiled? If the latter, then the cssu-testing repo should be enabled with cssu-thumb? If the former, then cssu-testing should not be enabled.
