I haven't solved the problem until now. The errors which the OP
mentioned appear in a early boot phase, most probably while executing
this script:

        local agent="/lib64/rc/sh/cgroup-release-agent.sh"
        mkdir /sys/fs/cgroup/openrc
        mount -n -t cgroup \
                -o none,nodev,noexec,nosuid,name=openrc,release_agent="$agent" \
		openrc /sys/fs/cgroup/openrc echo 1 > /sys/fs/cgroup/openrc/notify_on_release


The problem is that there are no denial messages, even if I disable the dontaudit rules.
But I'm absolutely sure SELinux is causing the problem, as everything works in permissive mode.
