[Starlingx-discuss] CENGN Build failures caused by new mock version 1.4.20

Hi folks, A new version of mock, 1.4.20, was recently released, and is getting picked up by the build container setup: https://opendev.org/starlingx/tools/src/branch/master/Dockerfile#L71 Unfortunately, our build tools are using a deprecated tool mockchain, which has now been dropped in this new mock-1.4.20, replaced with 'mock --chain'. This is causing the CENGN builds to fail. As a workaround, I'm trying to force the CENGN build to use mock-1.4.19. If this is successful, we could update the Dockerfile with this short-term workaround to unblock developers using a build container. The long-term solution, of course, would be to update the build tools to use 'mock --chain'. Cheers, Don. Don Penney, Developer, Wind River
