Comment 17 for bug 1663866

Currently this issue happens randomly, possible cause of this is running Reboot resource in parallel to Nova_config resource and causes nova.conf configurations to be missing as system rebooted before nova.conf is sync'd with filesystem. This issue might come in ubuntu as well.

From /var/log/messages file, It was clear nova_config resources was applied and Reboot resource also was applied immediately. With the fix, Reboot resource will be applied after all Nova_config resource has been completed.
