Yes, it better fits what I am more or less doing by hand.

I was proposing: guix pack -f docker -r foo generates the file: /gnu/store/<long-hash>-docker-pack.tar where the symlink foo to this file and the field REPOSITORY should be guix and the field TAG should `foo-<short-hash>` where <short-hash>` is let say 6 characters. I do not know if it is the right way.
