There is indeed a way to collect the revisions, and since the question has
come up before I just wrote a FAQ entry about it:

  https://wiki.yoctoproject.org/wiki/Technical_FAQ#How_do_I_collect_the_source_revisions_fetched_by_each_recipe.3F

This wouldn't actually store the revisions in a form that you could then put
into the image itself however. If you really wanted to do that you could in
theory run buildhistory-collect-srcrevs from a recipe and then package its
output though, I think that should work.

Cheers,
Paul
