Public bug reported: When bringing up the Azure datasource in cloud-init.service, cloud-init tries 'service start walinuxagent'.
That previously worked fine, and the agent would start and then would produce the certificate files that cloud-init needed (for ssh keys and things). I found this when testing SRU for 0.7.7-31-g65ace7b-0ubuntu1~16.04.1 but it is likely present also in 0.7.7-31-g65ace7b-0ubuntu1 (yakkety) Now, however we see a log like: Sep 14 14:53:18 smoser0914x [CLOUDINIT] DataSourceAzure.py[DEBUG]: Getting metadata via agent. hostname=smoser0914x cmd=['service', 'walinuxagent', 'start'] Sep 14 14:53:18 smoser0914x [CLOUDINIT] util.py[DEBUG]: Running command hostname with allowed return codes [0] (shell=False, capture=True) Sep 14 14:53:18 smoser0914x [CLOUDINIT] DataSourceAzure.py[DEBUG]: invoking agent: ['service', 'walinuxagent', 'start'] Sep 14 14:53:18 smoser0914x [CLOUDINIT] util.py[DEBUG]: Running command ['service', 'walinuxagent', 'start'] with allowed return codes [0] (shell=False, capture=True) Sep 14 14:53:18 smoser0914x [CLOUDINIT] util.py[WARNING]: agent command '['service', 'walinuxagent', 'start']' failed.
