I'm a cgroups noob, but my understanding is that both v2 and v1 coexist
in Ubuntu 22.04
(https://manpages.ubuntu.com/manpages/jammy/man7/cgroups.7.html). I have
another machine with Ubuntu 18.04, which also has (AFAIK) both versions
(https://manpages.ubuntu.com/manpages/jammy/man7/cgroups.7.html) and
where Slurm (slurm-wlm) 21.08.8-2 is installed, and I have no cgroups
issues there.

,----
| mount | grep cgroup
| cgroup2 on /sys/fs/cgroup type cgroup2 (rw,nosuid,nodev,noexec,relatime)
| cpuacct on /cgroup/cpuacct type cgroup (rw,relatime,cpuacct)
| freezer on /cgroup/freezer type cgroup (rw,relatime,freezer)
| cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer)

Thanks for any help/pointers,
