If this seems like deja vu, that is because it is. We had this
very same issue with the original CoreOS ramdisk. Since we don't
control the whole OS of the ramdisk, it only made sense to teach
the agent to umount the folder.
The folder is referenced already, and the agent does have safeguards
in place, but unfortunately this issue led to a rebuild breaking where
cloud-init, glean, and the agent were all trying do the right thing
as they thought, and there were just multiple /mnt/config folders
present in the OS. These are separate issues we also need to try and
remedy.
What happens is when the device is locked via a mount, the partition
table is never updated to the running OS as the mount creates a lock.
So the agent ends up thinking, in the case of a rebuild, that everything
including creating a configuration drive on that device has been
successful, but when you reboot, there is no partition table entry
for the new partition as the change was not successfully written.
This state prevented the workload from rebooting properly.
This change eliminates that possibility moving forward by attempting
to ensure that the cloud configuration folder is no longer mounted.

Ironic Python Agent
Team and repository tags
Overview
An agent for controlling and deploying Ironic controlled baremetal nodes.
The ironic-python-agent works with the agent driver in Ironic to provision the node. Starting with ironic-python-agent running on a ramdisk on the unprovisioned node, Ironic makes API calls to ironic-python-agent to provision the machine. This allows for greater control and flexibility of the entire deployment process.
The ironic-python-agent may also be used with the original Ironic pxe drivers as of the Kilo OpenStack release.
Building the IPA deployment ramdisk
For more information see the Image Builder section of the Ironic Python Agent developer guide.
Using IPA with devstack
This is covered in the Deploying Ironic with DevStack section of the Ironic dev-quickstart guide.
