One more question, as you can see `bootcmd` appears many times in
cloud.cfg, like cloud-init/cloud_config/cloud_final stage.

How can I run a command in a specific stage, like cloud_config ?

And  if I want to add datasource like openstack,  I just add lines
datasource:
    Openstack:
      metadata_urls: [ 'http://169.254.169.254:80' ]
      timeout: 5 # (defaults to 50 seconds)
     max_wait: 10 # (defaults to 120 seconds)

right?
