The really weird thing about this is that latest Fedora (by Red Hat, as is crun) doesn't even support cgroups v2. Or I couldn't figure out how to get it working. I had to disable v2 and go back to v1 and use runc.

Did you modified your bootloader with following parameter: systemd.unified_cgroup_hierarchy=1

In runtime, you should see the following:

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

btw, I use Arch (yeah I know, the standard adage)
