Description
It seems unfortunate that a new standard should use a method which unecesarilly limits the standard. With the .wh file approach, base images can no longer contain arbitrary data. This means, for example, that you cannot have an image with example OCI image-spec data stored in it. Is there any possibility of changing this to use, for example, a white out list instead. So that the files that made a layer would be:
VERSION
layer.tar
whiteouts
json
That would mean that truely arbitrary data could be stored in the images, which would be really nice :)
