Hello,

Cl=C3=A9ment Lassieur <clement@lassieur.org> skribis:

> Tests depending on 'guix-current' are expensive in terms of CPU and
> storage usage since we need to build (current-guix) and then store a
> couple of full system images.

[...]

> Is there another way to get those tests to work without depending on

These tests are indeed expensive.  However the motivation here is
precisely to test a complete installation procedure using the current
Guix in the installation image.  If we were to change that we=E2=80=99d be
testing something different and much less interesting.

So I think there=E2=80=99s not much we can do here.

Does that make sense?

(Note that all the other system tests use just whatever snapshot the
=E2=80=98guix=E2=80=99 package refers to, which is good enough for them bec=
ause they
don=E2=80=99t test things where Guix itself is involved.)

Thanks,
Ludo=E2=80=99.
