I read the thread at the time. Isn't this a very opinionated way to see
things? When reading the thread, I didn't feel there was a clear consensus.
Why would we then allow a single domain name? Let's say we were to
provide an OpenStack deployment for debian, and configured it with
"debian.net" as default domain, then what if I want a VM that would use
"debian.org" instead? This doesn't feel right at all...
Anyway, that's IMO not the issue. The issue is the (even short) hostname
not being resolvable with /etc/hosts not being edited by cloud-init.
