Hi!

Mathieu Othacehe <othacehe <at> gnu.org> skribis:

This is very cool, thumbs up!

That’d be awesome.

As discussed on IRC, builds per day should be compared to new
derivations per day.  For example, if on a day there’s 100 new
derivations and we only manage to build 10 of them, we have a problem.

BTW, in cuirass.log I noticed this:

Perhaps it can’t compute an average yet for these jobsets?

Thanks!
