Leveraging nix, nix-os to apply machine and home configurations

## Background

Having used a variety of infracture as code solutions - and having found them lacking in some areas, it is time to give nix a go.
Frustrations with other methods tend to be bitrot and config drift - very annoying to want to do a quick disaster recovery and find your have different versions of modules/utilities, breaking changes in code you didnt catch, etc.

## Getting started

To Install

```
# nixos-rebuild switch --flake github:truxnell/nix-config#HOST
```

## Goals

- [ ] Learn nix
- [ ] Mostly reproduce features from my existing homelab
- [ ] Replace existing ubuntu-based 'NAS'
- [ ] Expand usage to other shell environments such as WSL, etc
- [ ] handle secrets - decide between sweet and simple SOPS or re-use my doppler setup.

## TODO

- [ ] Github Actions update fly.io instances (Bitwarden)
- [ ] Bring over hosts
  - [ ] DNS01 Raspi4
  - [ ] DNS02 Raspi4
  - [ ] NAS
  - [ ] Latop
  - [ ] WSL
  - [ ] JJY emulator Raspi4
- [ ] Documentation!
- [ ] Add license
- [ ] Add taskfiles

## Hardware

## Applying configuration changes on a local machine can be done as follows:

```sh
cd ~/dotfiles
sudo nixos-rebuild switch --flake .
# This will automatically pick the configuration name based on the hostname
```

Applying configuration changes to a remote machine can be done as follows:

```sh
cd ~/dotfiles
nixos-rebuild switch --flake .#nameOfMachine --target-host machineToSshInto --use-remote-sudo
```
