Hi Cl=C3=A9ment,

I claim that these tests are useful and that having them under CI is a
good thing!

AFAICS the result of test.basic.*, test.mcron.*, etc. should be
unchanged when doc/*.texi are modified; if that=E2=80=99s not the case, we =
have
a bug. :-)   So there=E2=80=99s no waste of resources in this case.

However the tests in (gnu tests install) do entail a full build of Guix
from the checkout, among other things, at every commit, so they are
expensive.  They are useful though, so I=E2=80=99d rather keep it this way =
if
our build farm can keep up.

Thoughts?
