Hello Chris,

That’s a great idea, and indeed something that should have been done
earlier on.

Some comments:

It would be ideal if we could actually build something, but built
something cheap.

The way we do that in those tests is by:

  1. Using the ‘guile-bootstrap’ package as an example, under the
     assumption that it’s already available, does not require
     networking, and is built in one or two seconds.

  2. Using ‘--bootstrap’ or a similar option so that the derivations use
     ‘guile-bootstrap’ instead of ‘guile-final’, for the same reason.

See for instance tests/guix-package.sh.

Would you be willing to try something along these lines?

Thanks,
Ludo’.
