Comment # 1 on bug 1222450 from Aleksa Sarai

It seems that your machine doesn't have the memory controller enabled on
cgroupv2 (in fact it seems to only have pids enabled). What is the contents of
/sys/fs/cgroup/cgroup.controllers?

  cgroupControllers:
  - pids
  cgroupManager: systemd
  cgroupVersion: v2

Because systemd only allows unprivileged users to manage cgroupv2 cgroups, crun
can't do whatever cgroupv1 fallback it is presumably doing when you run podman
as root.

(FWIW, I can't reproduce this at all on my Tumbleweed machine. It's not a fresh
install though.)
