Expecting everything to be trouble free is not realistic, there can be problems. Development release is for testing to discover and correct as many problems as we can. The ISO file says “OpenMandrivaLx.4.0-beta” for a reason.

Even if current cooker development release is way better than OMLx 3 has ever been imho, always keep in mind: cooker is cooker!
