Ok, understood.

Thank you very much for this tip.
I have done exactly in this way and works perfectly and it's easy to manage.

However there's a part containded in the image_base.bb recipe:
    inherit core-image
    IMAGE_FEATURE_append = "..."

that I had to duplicate into the Image_with_graphicsupport.bb too.

It's not a problem but is it possible to put them in a common recipe like
packagegroup?
