Don't. Just don't. While Alma and Rocky promise the moon of 10 years of support and unreproachable governance, they are slow and inconsistent about releasing security fixes while CentOS 9 Stream releases them fast. Neither has the professionalism, track record, or deep benches of engineering teams to sustain themselves in the long term. I suspect neither Alma nor Rocky will survive 10 years.
How is it different than Redhat promising 10 years of support for Centos 8 then leaving me stranded?
