[yocto] Multiple ubifs partition

[Gabriele Zampieri]

Hi Ulrich,

ok, I guess I miss-understand how that class works. I thought that I had to
add the customization on my own image recipe.
So the correct way is to write a 'customization recipe' and install via
IMAGE_INSTALL? Can you provide an example?

Thanks,
Gabriele
