Public bug reported: [impact]
after systemd was changed to default to cgroupv2, any container started on a host that still uses legacy or hybrid cgroup mounts will result in a container that attempts to use unified cgroup but can't due to all the controllers being used as v1 in the host kernel. [test case] TBD [regression potential] container, or vm or bare metal, that incorrectly uses cgroupv1, or incorrect use of cgroupv2.
