That’s quite different from the ‘guix shell yt-dlp’ we started with
though.  :-)

Also, it very much depends on what ‘channels.scm’ contains.  ‘guix
time-machine’ does not support ‘--system’, but on x86_64-linux I get:

--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=63660f0febb -- shell yt-dlp -- yt-dlp --version
2023.06.22
--8<---------------cut here---------------end--------------->8---

I ran out of disk space (and out of time :-)) while running:

  guix time-machine --commit=63660f0febb -- shell \
    --rebuild-cache -s i686-linux yt-dlp -- yt-dlp --version

Anyway, it could be a problem with a channel other than ‘guix’, we can’t
tell so far.  Please let us know when you have the output of ‘guix
describe’ on that machine.

Ludo’.
