Already solved. Systemd always mounts an empty tmpfs at the 'cgroup'
mountpoint, and stuff is free to create subdirs there. Systemd itself
mount 'systemd' there.

I guess that covers all needs expressed here, and we are happy to
switch systemd over from /cgroup to /sys/fs/cgroup as soon as the
kernel carries the patch.

Thanks,
Kay
