Yes, we directly set /etc/hostname to contain the "short" hostname and set the FQDN in /etc/hosts as an alias for it bound to a (secondary) v4 loopback consistent with the default configurations for Debian/Ubuntu systems. We don't rely on hostname metadata or cloud-init to provide correct representations, as cloud providers like to mess around with things like default domains and that leads to an inconsistent experience across different environments. -- Jeremy Stanley
