You're right there is a chicken and egg problem when you add 
Raft to an existing project, and rebootstrap 
becomes a trick, but it's a plumbing trick.

The new member needs to generate and persist a globally unique
identifier as the first step. Later it can 
reintroduce itself to the cluster given this identifier
can be preserved in the new incarnation (popen + fork).
