Ok then, I'll give it a try.

Yep, it would be very helpful to track package closure size and
cross-compilation status using the CI. When sending a patch to Linux,
you get emails that inform you that you may have broken the build for a
specific architecture, in a specific configuration.

We would really need this kind of feedback for cross-compilation as very
few people actually use it, and it is really easy to break it. That's
something I'd like to discuss with Chris soon.

Thanks,

Mathieu
