Hello!

It was discovered while troubleshooting an issue on help-guix [0] that
Emacs cannot currently load its subr-x module (there are probably many
more) when used in a pure environment (or container) that doesn't
propagate bash and gzip, which it uses to decompress the said module.

The fix would be to patch Emacs' sources so those programs are referred
by their absolute store paths rather than simply being looked in PATH.

Yup, looks like the way to go.

I believe this was fixed by Leo Prikler in their commit
d13b46fae46fe0e0d529e67ffc7f4074440d1b6e (gnu: emacs: Add coreutils and
gzip to PATH).

Closing!
