IME it's much easier to automate using VMs if possible, but I'm open
to being convinced otherwise.

We could do something like that quite readily, I hope. Neil Williams
has already started setting up a Debian instance of LAVA [1] which is
designed to do exactly this kind of thing! See lave.debian.net if
you're interested.

Hi there

I can help with that :-)
bootstrap-vz is used for the official gce, ec2 and I think oracle (or will be used, not sure) images.
There are quite a few packages added to get the gce images working: optional ones from the manifest (but part of the official image) and mandatory ones
ec2 images are pretty basic: manifest herepackages here
oracle images are the same: manifest here, packages here

Keep in mind that those are only the packages that are explicitly added, the cloud_init plugin adds the cloud-init packages of course (ntp plugin adds ntp), and most of the images use grub for booting.
There are quite a few more places where some packages may be added: All in all the list should be: locales, sudo, openssh-server and isc-dhcp-{client,common}

Sorry, no :-/
But it would be a great idea to create a wikipage where all those deviations from standard debootstrap are documented!
Luckily the architecture of bootstrap-vz works in a way where you have small tasks that do one thing only (with descriptions to boot!).
When running `./bootstrap-vz --dry-run manifests/official/ec2/ebs-jessie-amd64-hvm.yml --log - --debug`, you get this. You can almost take that log and convert it into a document, it contains the full list of changes to an image :-)
