For that matter, "good" (in my opinion) OpenStack service providers
hand out relevant network configuration via DHCP/SLAAC which
shouldn't need any special handling at all. ConfigDrive has the
potential downside of being static for the lifetime of the server
instance, while the EC2 metadata service is a horrible SPoF which
you often see overloaded and timing out requests causing instances
to fail to boot entirely.
