Bootstrap without initial token

[Gabriel Ki]

Hi,

I was getting a runtime exception "Chose token 0 which is already in use by
..." when bootstrapping without initial_token.  So looking at
StorageService getBootstrapToken(), if the ring has more than 2 nodes and
all nodes are up, do I always have to specify initial token when adding new
nodes?  Did I miss anything?

Thanks,
