# installer

I have automated myself out of a job. Here's how to use the installer to create a new host:

1. Enable Secure Boot Setup Mode on the target device's UEFI menu - this will vary depending on the manufacturer

2. Boot into the installer

3. Connect to the internet with `sudo nmcli device wifi connect "<SSID>" [--ask]`

4. Run `sudo nix-install /etc/nixos -m install|repair -s -h host [-k key] [-c] [-r]"`

5. Enable Secure Boot on the device's UEFI menu.

## Reinstalling the Installer

1. Download a Minimal Live Nix ISO

- Visit the official NixOS website: [https://nixos.org/download.html](https://nixos.org/download.html).
- Download the "Minimal ISO image".

2. Burn the ISO

- On Windows, use [Rufus](https://rufus.ie) to burn the ISO to a USB drive.

- On Linux, use the `dd` command:

  ```bash
  sudo dd if=<path-to-iso> of=/dev/sdX bs=4M status=progress
  ```

3. Boot into USB

4. Connect to the Internet with `wpa_supplicant`

- Identify your network interface:

  ```bash
  ip link show | grep -E '^[0-9]+:' | awk '{print $2}' | tr -d ':'
  ```

- For an open network:

  ```bash
  wpa_supplicant -i "${interface}" -c <(wpa_passphrase "${ssid}") -B
  ```

- For a secured network:

  ```bash
  config=$(mktemp)
  wpa_passphrase "${ssid}" "${passphrase}" > "${config}"
  wpa_supplicant -i "${interface}" -c "${config}" -B
  rm "${config}"
  ```

- Obtain an IP address:

  ```bash
  dhcpcd
  ```

5. Clone the flake repository

   ```bash
   git clone git.karaolidis.com/karaolidis/nix
   cd nix
   ```

6. I really hope you had a backup of the keys, because you must copy them to the repository before the next step.

7. Run `nix --experimental-features "nix-command flakes" shell nixpkgs#disko nixpkgs#sbctl nixpkgs#jq -c bash hosts/common/configs/system/nix-install/install.sh . -m install -h installer -k personal -c`
