I just did this on GuixSD:
sudo -E guix package -p /usr -i bash coreutils
Now I have /usr/bin/env and /usr/bin/bash. I don’t think I needed it
before, though. “guix environment” is probably not the appropriate tool
for this.
I think it’s better to do this explicitly with profiles than to treat
/usr/bin/env somehow specially. Providing /usr/bin/env doesn’t
necessarily help — one would still have to have an interpreter installed
in an active profile.
