Hi core reviewers, I merged all master changes to centos8 feature branch with below patch list. Please help review them. After the patches get merged, we will try to enable layer build for centos8 feature branch, and continue CentOS 8.1 upgrade task. (There is Zuul failure with fault git, I will update the patch after fix is merged in master) https://review.opendev.org/#/q/topic:centos8-rebase+(status:open+OR+status:m...) Best Regards Shuicheng
