This currently has a couple of problems:

• docker-vm tpm is not enabled, after enabling it has several boot failures
• the docker share (/var/lib/docker) running in storage-vm has permission problems, resulting in the setup service to fail (this is after onboarding, when the images are downloaded).
• the vtpm feature + storagevm in ghaf seem to have some problems as well - e.g. /etc/machine-id is not available during early boot, which results in it being re-generated on each boot, and tmpfile setup fails because of unknown users, which could be a similar issue but with /var/lib/nixos storage

Have done some quick patch for reference:
