I've not had time to look at any of this. But the question I'm most curious about is how cgroup-v2 preserves the container invariant. That is, each container (namespace) should look like a 'real' machine. So just like userns allows to have a uid-0 (aka root) for each container and pidns allows a pid-1 for each container, cgroupns should provide a root group for each container. And cgroup-v2 has this 'exception' (aka wart) for the root group which needs to be replicated for each namespace. -- To unsubscribe from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
