Hi Maxim,

Note that this is not about =E2=80=98make check-system=E2=80=99 in general =
but
specifically about the tests in (gnu tests install).  These tests
require a =E2=80=9Ccurrent Guix=E2=80=9D, which is costly.

Interested readers are hereby invited to read Maxim=E2=80=99s benchmarks an=
d the
discussion here:

  https://issues.guix.gnu.org/issue/37305#7

:-)

Thanks,
Ludo=E2=80=99.
