Ok! One useful functionality of genimage seems to be that's its capable
of creating complex partitioning layouts. Of course we can re-implement
it in (gnu build disk-image), but I don't know how complex will it be.

Danny, I found the genimage files for each arm/aarch64 boards inside
Buildroot repository. They are a valuable source of information, but
regardless of the decision we take for (gnu build disk-image), we can
find a way to import them and store them as Guile records. 

I guess I'll start a small implementation to have a clearer view of this
topic.

Thank you all for the feedback,
