This QEMU image is not (yet) comparable to NixOS, because the latter provides
extra features, such as whole-system configuration (including services, etc.),
and whole-system transactional update and rollback. It is is cross-built using
Nix, and because of that, it uses per-package installation directories under
`/nix/store`.
