Download NixOS installation ISO

Notes:

  1. I assume that latest stable (e.g. 20.03) ISO will be used for installation.
  2. Default network configuration is VPN-only, so if you don't have plans to use it you need to change iptables rules (remove iptables -P OUTPUT DROP from networking.nix) and remove services.openvpn.servers.vpn from networking.nix.
  3. GUI settings is optimized for 3840x2160 on 15".
