Description of problem: === From bug 1393094#c9 === I found an issue with the new cloud-init - basically during the run of cloud-init it tries to set the hostname using hostnamectl but dbus hasn't started yet and it fails. We need to figure this out. from the debug log: ``` 2017-01-25 08:59:38,338 - util.py[DEBUG]: Running module set_hostname (<module 'cloudinit.config.cc_set_hostname' from '/usr/lib/python3.5/site-packages/cloudinit/config/cc_set_hostname.py'>) failed Traceback (most recent call last): File "/usr/lib/python3.5/site-packages/cloudinit/stages.py", line 776, in _run_modules freq=freq) File "/usr/lib/python3.5/site-packages/cloudinit/cloud.py", line 54, in run return self._runners.run(name, functor, args, freq, clear_on_fail) File "/usr/lib/python3.5/site-packages/cloudinit/helpers.py", line 187, in run results = functor(*args) File "/usr/lib/python3.5/site-packages/cloudinit/config/cc_set_hostname.py", line 47, in handle cloud.distro.set_hostname(hostname, fqdn) File "/usr/lib/python3.5/site-packages/cloudinit/distros/__init__.py", line 84, in set_hostname self._write_hostname(writeable_hostname, self.hostname_conf_fn) File "/usr/lib/python3.5/site-packages/cloudinit/distros/rhel.py", line 130, in _write_hostname util.subp(['hostnamectl', 'set-hostname', str(hostname)]) File "/usr/lib/python3.5/site-packages/cloudinit/util.py", line 1850, in subp cmd=args) cloudinit.util.ProcessExecutionError: Unexpected error while running command.

I pulled the patch from the commit in the first comment of this BZ and applied it to cloud-init 0.7.8 in Fedora and built a scratch build: https://koji.fedoraproject.org/koji/taskinfo?taskID=17405006 Version-Release number of selected component (if applicable): cloud-init-0.7.9-1.fc26
I added a potential fix to cloud-init-0.7.9-2.fc26 by removing DefaultDependencies=no from cloud-init.service. Note that there is still discussion on this issue occurring upstream.
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.

This message is a reminder that Fedora 27 is nearing its end of life. On 2018-Nov-30 Fedora will stop maintaining and issuing updates for Fedora 27. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '27'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 27 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
