As far as I understand it, cloud-init handles early initialization of a cloud/VM instance.
Ive been using it to help build KVM VMs and it works really well.

One aspect of cloud-init I don't understand is what happens once its done the initial creation of the instance.

• Does it automatically disable itself so it never runs again?


• 
  

  Can it execute again under certain circumstances (e.g. on a change to /etc/machine-id)? I'm pretty sure I forced it to re-run at some point by running

  
  
  

  sudo rm -rf /var/lib/cloud/*
  

  
  



• Is it designed so that I should be uninstalling cloud-init once my instance has been built and its gone into production, or does cloud-init stay installed (doing nothing) even after its been instantiated?

  "Initialization" is not the same as "installation".
