[Podman] OCI permission denied from '--uidmap'

Hi guys. If I use 'uidmap' then container in a pod fails to start/run with: Error: error stat'ing file `/var/lib/containers/storage/overlay-containers/18df20ff42cbe9c48807ccd1a529696b93638d81a431161a94d7caeb1f2b6c2b/userdata/shm`: Permission denied: OCI permission denied Quite a few "OCI permission" around the net but none relating to that above I could find. What might be a solution for the issue? many thanks, L.
