Hi

After upgrading to >=sys-apps/systemd-243 I found out that docker was unable to detect cgroups and was thus unable to start:

août 12 08:39:04 yazd dockerd[2128]: time="2019-08-12T08:39:04.534612423+02:00" level=warning msg="Unable to find cpu cgroup in mounts"
août 12 08:39:04 yazd dockerd[2128]: time="2019-08-12T08:39:04.534617330+02:00" level=warning msg="Unable to find blkio cgroup in mounts"
août 12 08:39:04 yazd dockerd[2128]: time="2019-08-12T08:39:04.534622292+02:00" level=warning msg="Unable to find cpuset cgroup in mounts"
août 12 08:39:04 yazd dockerd[2128]: time="2019-08-12T08:39:04.534626458+02:00" level=warning msg="mountpoint for pids not found"

It turns out that this is due to systemd defaulting (again) to hierarchical cgroups:

https://github.com/systemd/systemd/blob/v243-rc1/NEWS#L60

Rebuilding systemd with the 'cgroup-hybrid' USE flag fixed the issue.

Shouldn't we default this USE flag while a broader response to the cgroup hierarchy is in place for us?

Thanks
