If the hostname changes from, for example, openhpc-login-0.novalocal to openhpc-login-0 due to reboot, the management server fails to start.

I ended up spending another couple of hours trying to work out why the /mnt/openhpc mount was failing to mount. In the end, it ended up being down to a badly configured /etc/hosts file which had a different IP address for the openhpc-login-0 node, the node hosting the management server. This issue is simply here as a cautionary tale... not sure if it can be resolved but we can probably add some simple smoke tests before the provisioning begins to address the issue.
