I committed this test by mistake, which is why the commit log doesn’t
mention it, and also the reason why it doesn’t work.  ;-)

My bad!

(Glad you found it though; it suggests a backdoor wouldn’t go unnoticed
for too long…)

Here the test fails during the installation phase, so there’s no
additional log file produced.  You should find a couple of
/tmp/guix-build-* directories, but they are of no use; everything is in
the build log above (here, “cat /mnt/etc/config” fails, which aborts the
installation.)

No KVM problem here: the transcript that we see above is that of the
installation process running in QEMU/KVM.  See (gnu tests install) for
the complete installation script.

This test was meant to test the patch at <http://bugs.gnu.org/21843>,
which is not committed yet.

I’ll try to resume work on this since I messed up in the first place.

Thanks!

Ludo’.
