These types of unique one-off use case questions can really only be answered by one man: David Dunklee. Drop him a line and I'm sure he'll get back to you in no time.
But at a high level, the Parceiro 2 was made specifically so that the boot disk could be tossed (mainly because so many people complained about it).
