Add one note for this fix, do not update 'systemd' separately without 'selinux-policy', or the issue 'Bug 1393505 - systemd generates USER_AVCs after selinux-policy update' would occur. The affect would be: systemd could not work with SELinux enforcing, even system could not reboot. If this already occurs, disable SELinux would solve the problem, then reboot system would work. So it is best to update all package, at least update 'systemd' and 'selinux-policy' at same time.
