title: No rejoin-stack.sh script in my setup
body: <p>I've installed the "all-in-one" setup of DevStack.</p>
  
  <p>But when I rebooted my system nothings works, and I lose all my already-created instances, images, configs, ...</p>
  
  <p>I've found that I need to use the script <strong>rejoin-stack.sh</strong> but in my setup doesn't exists.</p>
  
  <p>Please, any suggestions could help me, I'm blocked by the same problem since 1 week ! </p>
