|

|
||||
1. Boot the server from the USB.
|
||||
2. If you did not bake WiFi into the ISO, attach Ethernet or (on graphical installer) join Wi‑Fi so the machine has network.
|
||||
3. Clone this repo (or copy the install script onto the machine). For example:
|
||||
3. Run **one** of the following (shortest first).
|
||||
|
||||
**Shortest — fetch and run (no clone step):**
|
||||
Exact URL (watch for typos: **.com** not .con, **usb** not ush, **DannyDannyDanny** with three capital Ds):
|
||||
|
||||
```bash
|
||||
nix run --extra-experimental-features "nix-command flakes" nixpkgs#git -- clone https://github.com/USER/dotfiles.git /tmp/dotfiles
|
||||
cd /tmp/dotfiles
|
||||
curl -sL https://raw.githubusercontent.com/DannyDannyDanny/dotfiles/server-installer-usb/scripts/bootstrap-install.sh | sudo bash
|
||||
```
|
||||
|
||||
4. Run the install script (it will prompt for hostname and target disk):
|
||||
If you see `bash: 404: command not found`, the URL was wrong or the branch doesn’t exist. Check the URL, or verify first: `curl -sL "THE_URL_ABOVE" | head -1` should show `#!/bin/bash`, not HTML.
|
||||
|
||||
To type less, create a [git.io](https://git.io) short link once (paste the raw URL above), then on the machine run: `curl -sL https://git.io/YOUR_CODE | sudo bash`.
|
||||
|
||||
**Alternative — clone then run** (if you prefer not to pipe curl to bash):
|
||||
|
||||
```bash
|
||||
sudo ./scripts/nixos-server-install.sh
|
||||
nix run --extra-experimental-features "nix-command flakes" nixpkgs#git -- clone https://github.com/USER/REPO.git /tmp/dotfiles && cd /tmp/dotfiles && git checkout server-installer-usb && sudo ./scripts/nixos-server-install.sh
|
||||
```
|
||||
|
||||
The script uses the flake from the current repo by default (`path:$(pwd)/nixos`). To use the flake from GitHub instead:
|
||||
If you see `command not found` when running the script, use `sudo bash ./scripts/nixos-server-install.sh` instead of `sudo ./scripts/...`.
|
||||
|
||||
```bash
|
||||
sudo FLAKE_REF=github:USER/dotfiles ./scripts/nixos-server-install.sh
|
||||
```
|
||||
|
||||
5. When disko creates the LUKS volume, enter the encryption passphrase when prompted.
|
||||
6. When the script finishes, remove the USB and reboot. The new NixOS system will have LUKS root and the hostname you chose.
|
||||
4. When prompted: enter **hostname** (e.g. `phantom-ship`), then **target disk** (default `/dev/sda`), then **y** to proceed. When disko creates the LUKS volume, enter your encryption passphrase.
|
||||
5. When the script finishes, remove the USB and reboot. The new NixOS system will have LUKS root and the hostname you chose.
