Getting this error:

 This seems to have started happening after I upgraded to Debian 11. 

 I commented out NanoCPUs and restarted, now I'm getting this error:

 So this has something to do with cgroupv2? 

 This is using Arvbox, so this is Docker-in-Docker, so it is also possible something changed so that cgroups is no longer properly exposed from the host environment ito the container environment.
