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.
