Hi,
For SIGs building el8 packages in CBS using ruby (other modules may be affected too), be aware of an unexpected behavior I'm finding where non-default module (ruby:2.6) is enabled instead of default on (ruby:2.5) for packages requiring ruby. This is causing installability issues in my case and blocking some builds.
I've reported it in https://bugs.centos.org/view.php?id=17013 . It may be good to get feedback from other SIGs experiencing similar issues on this bug.
Best regards,
Alfredo
