BSD can do BSD containers with Jails for more than a decade now?
Due to innate features of a container, it can be of the same OS of the host running on the system, since they have no kernel. Otherwise you need to go the VM route.
In this context (OCI containers) that seems very inaccurate. For instance, ocijail is a two year old project still considered experimental.
FreeBSD has beta podman (OCI) support right now, using freebsd base images not Linux. It is missing some features but coming along.
