!   2) If no such flag exists, the Init.init() implementation may
       temporarily enable interrupts. It MUST NOT call any other
       component or return unless it has re-disabled interrupts.
  
! The Init.init() command MUST NOT call any commands or signal any
! events, except for calling Init.init() on other components. A

! it needs to enforce a temporal ordering on initialization. If a
  component A depends on another component, B, which needs to be 
  initialized, then A SHOULD wire B's Init directly to the boot
