This requires a lot of restructuring. The .nix files have to be bundled
together with the python files, so they need to follow python's module
system structure.
I ran `nix-fast-build --no-link -j 2 --eval-workers 3 --flake .#checks`
and it succeeded, so I'm reasonably confident I changed everything as
required.
In the section `### Generating the `.raw` VM Image` in step 3.
It is written that the raw image file created is named `vdb`, but in the file [simple-efi.nix](a816daa384/example/simple-efi.nix) the first time `vdb` is mentioned is in `disko.devices.disk` not in `disko.disks` so I assumed that the file [simple-efi.nix](a816daa384/example/simple-efi.nix) was updated it the part about `disko.disks` is a mistake. Otherwise, I would really like to know what I am not understanding here 😁
