The VM Import service targets a very specific use case involving
migration of existing virtual machines from on-premesis environments to
EC2. It isn't a general purpose AMI creation tool.

I didn't actually realize that VM Import claimed support for any Debian
version, but apparently it supports "Debian 6.0.0-6.0.8, 7.0.0-7.8.0,
8.0.0". IMO it should either update that list to reasonably modern
Debian versions and drop the old EOL versions, or just drop Debian
support altogether if they can't update the list.

We don't use VM Import. We use the ImportSnapshot API. See the
following:
