That's interesting, I would say the opposite though. ZK uses the myid file when starting to know which node in the config file corresponds to itself. If the myid file doesn't match a "server.X" entry in the config file, then I imagine it would fail to start successfully, not knowing which ip/ports are for itself. Maybe someone who isn't guessing should answer though.
