- [ ] base should automatically be set as the default (dont do anything with the default)
- [ ] try to remove common foot guns, ie abort if the user provides the home-manager or microvm nixosModules
      since cerulean ALREADY provides these

- [ ] deploy port should default to the first port given to `services.openssh`

- [ ] use the Nix module system instead of projectOnto for `cerulean.mkNexus`
- [ ] create an alternative to nixos-install called cerulean-install that
      allows people to easily bootstrap new machines (and host it on dobutterfliescry.net)

- [ ] find an alternative to `nix.settings.trusted-users` probably
- [ ] add the ceru-build user, 
- [ ] add support for github:microvm-nix/microvm.nix
- [ ] add support for sops-nix

- [ ] it would be cool to enable/disable groups and hosts
- [ ] find a standard for how nixpkgs.nix can have a different base per group

- [ ] go through all flake inputs (recursively) and ENSURE we remove all duplicates by using follows!!

- [X] rename nixos-modules/ to nixos/
- [X] ensure all machines are in groups.all by default

- [X] fix nixpkgs.nix not working (default not respected)
- [X] remove dependence on nixpkgs

- [ ] allow multiple privesc methods, the standard is pam_ssh_agent_auth

## Low Priority
- [X] rename extraModules to modules?
- [X] rename specialArgs to args?

- [ ] make an extension to the nix module system (different to mix)
      that allows transformations (ie a stop post config, ie outputs, which
      it then returns instead of config)


- [ ] what if we automated the process of replacing windows with Nix??
      then push this to nixos-anywhere or nix-infect lmaooo

- [ ] patch microvm so that acpi=off https://github.com/microvm-nix/microvm.nix/commit/b59a26962bb324cc0a134756a323f3e164409b72
      cause otherwise 2GB causes a failure

- [ ] rewrite the ceru cli in rust
- [ ] make `ceru` do local and remote deployments

- [ ] support `legacyImports` 

```nix
# REF: foxora
vms = {
  home-assistant = {
    autostart = true;
    # matches in vms/*
    image = "home-assistant";
    options = {
      mem = 2048;
    };
  };
  equinox = {
    image = "home-assistant";
  };
};
```
