#### LyonOS V2 - New and *improved!*

LyonOS is my personal Linux distribution based on NixOS. This repository contains all the flake that I use on my laptop, desktop, and VMs.

---
### Setup
```
git clone https://github.com/ArcoNightshade/LyonOS-V2 ~/.lyonos && rm -rf ~/.lyonos/.git
```

```
cp /etc/nixos/hardware-configuration.nix ~/.lyonos/profile/workstation/hardware.nix
```

Set your username.
```
nano ~/.lyonos/flake.nix
```

Specify your drive type (scroll to the bottom)
```
nano ~/.lyonos/compose.nix
```

Set your password, use this to get the hash
```
mkpasswd -m sha-512 <password>
```

Place the output in `hashedPassword = "";`
```
nano ~/.lyonos/compose.nix
``````

Rebuild & reboot to be safe, or just switch.
```
sudo nixos-rebuild boot --flake ~/.lyonos#workstation
```
---

### Commands
```
sudo nixos-rebuild switch --flake ~/.lyonos#workstation
```
nixos-rebuild has a few options:
* switch  : switches to the new configuration immediately
* boot    : builds the next generation but does not switch until reboot
* dry-run : only evaluates the code to see if it works
* test    : switches to the new generation but does not save it to the boot menu

```
sudo nixos-rebuild switch --flake ~/.lyonos#workstation --rollback
```
Rolls back to the previous generation.

```
sudo nix-collect-garbage
```
Deletes all previous generations so you don't run out of space.

```
sudo nix flake update --flake ~/.lyonos#workstation
```
Update system.

```
nix-shell -p cowsay
```
Installs software to the shell (not the system) and is discarded when the shell (terminal) is closed.

Copy paste to compose.nix and add `config` to `{ settings, ... }:` => `{ settings, config, ... }:`
```
  hardware.nvidia.open = false;
  hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.production;
  boot.blacklistedKernelModules = [ "nouveau" ];
