If it is clear for you that this is a requirement, please state it 
explicitely for the "multiple init systems supported" option:

 * Any supported init system must support switching a running system
   from any other supported init system to this init system, as well
   as switching a running system from this init system to any other
   supported init system. This switch is expected to require a reboot.
