There's a merge request for a Docker backend for autopkgtest, which I
suspect can easily be turned into a Podman backend since they're broadly
command-line compatible. Getting that into a mergeable state is on my
(long) to-do list. If it works for both, I think ideally we'd have an
autopkgtest-virt-podman that just runs
`exec autopkgtest-virt-docker --podman "$@"`, for better discoverability.
One major blocker for merging a Docker backend is defining exactly what
the isolation-container restriction means, because at the moment some
packages assume that it means a "full-system" container with a
fully-featured init system (like lxc or lxd, where the container usually
"boots" with systemd, Upstart or sysvinit), and Docker is not usually
used in that way.
