> There seem to be a few intermediate states that can be added to improve the
> stability of the NM container state machine.
> For. eg:
> * The REINITIALIZING should probably be split into REINITIALIZING and
> REINITIALIZING_AWAITING_KILL.
> * Container updates are currently handled in the ContainerScheduler, but it
> would probably be better to have it plumbed through the container state
> machine as a new state, say UPDATING and a new container event.
> The plan is to add some extra tests too to try and test every transition.
