A customer reused hardware that had previously deployed a RHEL Overcloud-controller which places metadata on the disk as a legitimate source, that cloud-init looks at by default. When the newly enlisted node appeared it had the name of "overcloud-controller-0" vs. maas-enlist, pulled from the disk metadata which had overridden MAAS' metadata. Commissioning continually failed on all of the nodes until the disk metadata was manually removed (KVM boot Ubuntu ISO, rm -f data or dd zeros to disk).
