The important thing is that the last node to go down gets started first. 
This is imposed by mnesia for the simple reason that the last node will 
have the most recent data, and the others will be able to synchronize 
after him. It doesn't matter if the others are started in a different order.

The next question might be "what if for some reason I can't restart that 
node"? In that case right now the situation is pretty ugly and there 
isn't an easy way out. We're planning to solve this in the next release.
