**Personal NixOS + Home Manager flake.** Builds for `x86_64-linux` and `aarch64-linux`. Uses [flake-parts](https://flake.parts/).

| `desktop` | x86_64 | Niri | Full graphical |
|
|
| `laptop` | x86_64 | Niri | Battery, bluetooth, location |
|
|
| `tty` | x86_64 | — | Headless server |
|
|
| `hetzner` | x86_64 (24.05) | — | Isolated server, disko + sops-nix |

## Quick Install (with disko — recommended)
|
|
|
|
```bash
|
|
# Boot NixOS minimal ISO, then:
|
|
sudo -i
|
|
git clone --depth 1 https://github.com/someone/shin /mnt/etc/nixos
|
|
|
|
# Auto-partition, format, mount (replace 'laptop' with 'desktop'/'tty')
|
|
nix --extra-experimental-features "nix-command flakes" \
|
|
run github:nix-community/disko -- \
|
|
--mode destroy,format,mount /mnt/etc/nixos/hosts/aesthetic/disko-config.nix
|
|
|
|
# Generate hardware config
|
|
nixos-generate-config --dir /mnt/etc/nixos/hosts/aesthetic
|
|
rm /mnt/etc/nixos/hosts/aesthetic/configuration.nix
|
|
|
|
# Install
|
|
cd /mnt/etc/nixos
|
|
nixos-install --flake .#laptop
|
|
```
|
|
|
|
**BIOS vs UEFI:** Set in `hosts/aesthetic/default.nix`:
|
|
```nix
|
|
boot.loader.limine.bootMode = "bios"; # or "uefi"
|
|
```
|
|
|
|
---
|
|
|
|
## Post-Install: Secrets
|
|
|
|
```bash
|
|
# Reboot into new system, then:
|
|
sops secrets/secrets.yaml
|
|
# Fill in:
|
|
# hetzner_server — SSH private key for root@severijnse.eu
|
|
# gitea_laptop — SSH private key for git@git.severijnse.eu:222
|
|
# discordo, openrouter, github, twt, gemini, context7, exa — API tokens
|
|
sudo nixos-rebuild switch --flake /etc/nixos#laptop
|
|
```
|
|
|
|

|
|
|
|
## Daily Workflow
|
|
|
|
```bash
|
|
# Rebuild after changes
|
|
sudo nixos-rebuild switch --flake /etc/nixos#laptop
|
|
|
|
# Or with nh (cleaner)
|
|
NH_FLAKE=/etc/nixos nh os switch
|
|
|
|
# Update flake inputs
|
|
nix flake update --flake /etc/nixos
|
|
|
|
# Format Nix code
|
|
alejandra /etc/nixos
|
|
```

## sops-nix Details
|
|
|
|
- Encrypts `secrets/secrets.yaml` with **age** using the SSH host ed25519 key (`/etc/ssh/ssh_host_ed25519_key`)
|
|
- Auto-decrypts to `/run/secrets/` at activation
|
|
- Fish loads secrets from `/run/secrets/` via `home/terminal/shell/fish.nix`
|
|
- SSH config references `/run/secrets/hetzner_server` and `/run/secrets/gitea_laptop`
|
|
|
|
To re-encrypt for a new host key:
|
|
```bash
|
|
cd /etc/nixos
|
|
nix shell nixpkgs#sops -c sops --encrypt --age "$(nix shell nixpkgs#ssh-to-age -c ssh-to-age < /etc/ssh/ssh_host_ed25519_key.pub)" secrets/secrets.yaml > secrets/secrets.yaml.new
|
|
mv secrets/secrets.yaml.new secrets/secrets.yaml
|
|
```
