Well, as I've expressed in
we could make it so jigdo supports sticking data that has been
published to a tree in some form. To generate the jigdo definition, the
squash would need to be opened and the resulting bits would need to be
hashed. Thus, putting the data back together would also involve
creating a squashfs and sticking data into it. I've not looked into
this outside of just conceptual design. If there are any squashfs gurus
that would like to comment, please do.
