I replaced Centos8 with Amazon Linux 2 ("amazon linux extras" provides a working docker installation) for exactly the same reason. I like the idea of podman and buildah and I wish them well, but for the time being I can't afford to debug the missing pieces and subtle failures.
We have had to replace RHEL systems with Ubuntu to keep some of our applications running as they fail on Podman. A major problem is also that podman-compose is far from feature parity with docker-compose.
