		+	Das master-overlay darf nicht direkt auf den sourcen liegen, sondern auf einem Snapshot derer, so kann man während dem bauen an den sourcen weiter arbeiten.
		+
		+	Die Tasks dürfen auch nicht direkt auf dem master-overlay arbeiten.
		+	Nur Tasks, die aus dem selben Task-Set (Tasks die parallel ausgeführt werden dürfen) sind, können auf dem selben snapshot arbeiten.
		+	D.h. ein neuer master-snapshot muss nur erzeugt werden, wenn ein neues Taskset berechnet wird.
