The image hash already depends on `guix pack` command-line options
--entry-point, --save-provenance, and --symlink as well as package
transformations, --no-grafts, and --system. Since building a
bit-to-bit reproducible docker image already requires replaying the
command-line options, adding an optional name would not reduce
reproducibility.
