No it doesn't... The init process keeps running. This is something I 
have contacted the OpenRC author about.
However, his question is what init should do when it is rebooting or 
halting the machine.
When I simply kill init after a few minutes, the VZ state of the 
container is 'mounted', which it should only be when rebooted from 
inside the container.
That is how my question came to mind: is there some signal init should 
send to OpenVZ or the 'hardware' that it is shutting down or rebooting?

Thanks,
