Fernando, I have put a lot of energy into answering these questions today. Please read from the list archives what I have said, particularly in the sub-thread "Brief summary of live-build and live-wrapper development status" and if that leaves you with any lingering questions, don't hesitate to ask. In short, no, it is not time yet to migrate to live-wrapper and there is no pressing need to do so. Continue using live-build for now. Ben
