Actually I suspect I know what happened. find_real_cgroup() doesn't
look like how I remember doing it. Could you try the below
(untested) patch? It'll enter you in a per-container subdir in
the name=systemd cgroup, which we didn't use to do. But it may
be what we want to do in the future case of unprivileged starts
anyway.
[PATCH 1/1] find_free_cgroup: don't ignore cgroup mounts without subsystems
If we are storing it, then store our current cgroup. We might
want to ignore it, but failing was the wrong thing to do in any
case.

Sorry to say, but the patch did not help. Attached is the new debug.out.
