testing/podman: OCI runtime error
After installing podman (v1.9.3 on Alpine 3.12 x86_64 in a VM) and accounting for the CNI plugins issue (!9350 (closed)), I'm unable to start any containers.
$ podman run -d --rm -p 8080:80 docker.io/nginx:latest Error: invalid file system type on '/sys/fs/cgroup': File exists: OCI runtime error
If there are any additional missing and undocumented steps I'd suggest either providing them with the package or create a wiki page for them.
Poking @mpolanski since he/she is the maintainer.
