I am not familiar with rauc, so sorry for what is perhaps a silly
question: is squashfs needed in all cases, or just for a certain bundle
format, or certain use cases ?

I'm just trying to figure out if we really want this to be a mandatory
dependency, or rather not enforce it, and simply document that it might
be needed.

Thanks for your feedback,

Thomas
