Correct, I think this is a pycloudlib issue.

Title:
  cloud-init exits early on ec2 after reboot

Status in cloud-init:
  Invalid

Bug description:
  Possibly duplicate of or related to bug #1890528 .

  When rebooting an ec2 instance after a "cloud-init clean --logs",
  "cloud-init status --wait --long" will exit early with non-0 status,
  but a later subsequent run of "cloud-init status --wait --long" will
  wait and return cleanly.

  To reproduce, create an example test file at tests/integration_tests/test_example.py:
  ```
  def test_ec2(client):
      client.execute('cloud-init clean --logs')
      client.restart(raise_on_cloudinit_failure=True)
  ```

  Run with:
  ```
  export CLOUD_INIT_PLATFORM=ec2
  export CLOUD_INIT_CLOUD_INIT_SOURCE=NONE

  pytest -s tests/integration_tests/test_example.py
  ```

  Relevant output from failure:
  ```
      def _wait_for_cloudinit(self, *, raise_on_failure: bool):
          """Wait until cloud-init has finished.
      
          :param raise_on_failure:
              When `True`, if the process waiting for cloud-init exits non-zero
              then this method will raise an `OSError`.
          """
          self._log.debug('_wait_for_cloudinit to complete')
      
          result = self.execute("cloud-init status --help")
          has_wait = "--wait" in result.stdout
      
          if has_wait:
              cmd = ["cloud-init", "status", "--wait", "--long"]
          else:
              # runlevel 'N 2' supports distros without recent cloud-init
              # (e.g. trusty).
              runlevel_result = (
                  '[ "$(runlevel)" = "N 2" ] && '
                  "[ -f /run/cloud-init/result.json ]"
              )
              cmd = (
                  "i=0; while [ $i -lt {} ] && i=$(($i+1)); do {} && exit 0;"
                  " sleep 1; done; exit 1".format(
                      self.boot_timeout, runlevel_result
                  )
              )
          result = self.execute(cmd, description='waiting for start')
      
          if raise_on_failure and result.failed:
              raise OSError(
                  'cloud-init failed to start: out: %s error: %s' % (
  >                    result.stdout, result.stderr
                  )
              )
  E           OSError: cloud-init failed to start: out: .... error:

  ../pycloudlib/pycloudlib/instance.py:427: OSError
  ```

  I see no indication in the logs of any problem or failure.
