The current approach of drone-service which is being installed as a service bundle is: try to trim the size down to max.
This works in simple cases but fails when test bundles are more complex. In this case unneccessary special care must been taken about the manifest which is counter productive to what paxdrone wants.
Instead, a new assembly bundle will provide all packages. The drone-bundle (built on the fly) gets much simpler with respect to the manifest now.
