Comment 1 Ben Howard 2020-07-10 19:35:52 UTC 
The fix in https://github.com/openshift/machine-config-operator/pull/1914 addresses three problems:
- race condition between dhclient having 64-characters hostnames that are too long for the cluster
- slow transient hostname from reverse DNS
- network manager failing to set hostname when the dhcp client name is too long
- /etc/hostname have a name longer than 63 characters.
