Hi, I am experiencing a similar situation without the container. At work, I need some special Emacs packages, that I don't need/want in my normal setup, so I do `guix shell -m manifest.scm -- emacs'. Even with the directory added to the good noodles list, `guix shell -- emacs' fails, probably because Guix assumes it has arguments when those really are just the command to run. IOW the check for "when is implicit okay" might be too narrow for this use case.
Cheers
