Hi guys.

I've noticed that recently, for a while, only these controllers are enabled by default:

-> $ cat "/sys/fs/cgroup/user.slice/user-$(id -u).slice/user@$(id -u).service/cgroup.controllers

If I remember correctly 'cpu' was also available by default not long time ago.

Would anybody know why such change, what's rationale behind it? many thanks, L.
