installer

I have automated myself out of a job. How to use:

1. Boot into installer

2. Unlock luks partition

3. Connect to the internet with nmcli

• Scan for available networks:

  nmcli device wifi list
  

• For an open network:

  nmcli device wifi connect "<SSID>"
  

• For a secured network:

  nmcli device wifi connect "<SSID>" password "<password>"
  

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

Reinstalling the Installer

1. Download a Minimal Live Nix ISO

• Visit the official NixOS website: https://nixos.org/download.html.
• Download the "Minimal ISO image".

2. Burn the ISO

• On Windows, use Rufus to burn the ISO to a USB drive.

• On Linux, use the dd command:

  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:

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

• For an open network:

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

• For a secured network:

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

• Obtain an IP address:

  dhcpcd
  

5. Clone the flake repository

   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#jq -c bash hosts/common/configs/system/nix-install/install.sh nix -m install -h installer -k personal -c
