Ludo recently fixed a problem with the exit status of "guix challenge".
So now it (correctly) returns zero if the challenge is succesfull, and
non-zero otherwise.
It would be very useful however, if it would return a *different*
non-zero if the challenge fails from when the challenge is inconclusive.
For example, the current behaviour seems to be:
Unsuccessful Challenge:

I suggest returning 2 in the inconclusive case.
