I know you're probably a long, long way from worrying about wifi, but when you
get to that point, I suggest taking a look at running `eiwd` in the netvm:

  https://github.com/illiliti/eiwd/
  https://github.com/NixOS/nixpkgs/pull/208844

- It is way more robust than wpa_supplicant.
- (unlike iwd) it does not require plumbing a dbus connection from the hostvm to
  the netvm (nor all the attack surface that would entail).
- You control it by simply editing its state files, which it watches with
  `inotify()`.
- It has zero runtime dependencies!
- `pkgsStatic.eiwd` builds (caveat: I have not tested it)
  - You should be able to boot a VM with `init=/nix/store/...-eiwd/bin/eiwd`
    and run it as PID 1 (note: I have not tried this).

I've been running this on my daily driver laptop for the last few weeks and am
extremely happy with it.
