-----------------------------------
> To sum it up, I dont think it is necessary a pure distributed locking

> cluster. What is your opinion?
Would be enough if launch-cluster would gracefully exit if there is at least
one machine running in the same group (with the same cluster-name)?
> Ensure the same cluster can't be started twice
