-Subject: [PATCH] core: don't use the unified hierarchy for the systemd cgroup
- yet
-
-Too many things don't get along with the unified hierarchy yet:
-
- * https://github.com/opencontainers/runc/issues/1175
- * https://github.com/docker/docker/issues/28109
- * https://github.com/lxc/lxc/issues/1280
-
-So revert the default to the legacy hierarchy for now. Developers of the above
-software can opt into the unified hierarchy with
-"systemd.legacy_systemd_cgroup_controller=0".
