Prebuilt system of master does not scale
Ce current master takes 7GB. If we add support for X, Moodle, Kolibri, etc... et will become bigger and bigger. This can be quite a waste of storage if all of this is not needed by the user.
We have chosen the system because this is quick to install and really reliable, which is great... but maybe we could find a better alternative where we could keep these advantages without potentially losing so much mass storage?
