I am trying to build an iso file for an older laptop with an i686 cpu architecture with some application like tailscale and network manager (for wifi) preconfigured. My main machine is a x86_64-linux machine (NixOS or Fedora). I saw that I have to set boot.binfmt.emulatedSystem on the nixos-generators github page.
Is that correct to assume, that I need to do it on my NixOS machine and that I have to set :
boot.binfmt.emulatedSystem = [ "i686-unknown-linux-gnu" ]
in my configuration.nix for me to be able to create an iso using:
nixos-generate -f iso -c /etc/nixos/configuration.nix
