Public bug reported: On Ubuntu Core 18, the memory cgroup is disabled, it seems that it needs to be manually enabled. I was able to enable it by adding `cgroup_enable=memory cgroup_memory=1` to the kernel command line, but on Ubuntu I think the memory cgroup should be enabled by default shouldn't it?
