Just "food for thought": git-annex metadata allows users to attach
arbitrary metadata to their annexed files, «metadata is stored in the
git-annex branch, and so is automatically kept in sync with the rest of
git-annex's state»

Being content-hashed, each file will persintently keep its metadata even
in case of renames (in the git-annex "filesystem" scope)

I doubt this could be applied to `guix pack`, but it's an intereting
approach to "sidecar" metadata

Happy Guix! Gio'.
