pre-reqs:

• for non-nixOs systems that have the nix package manager installed:

  • enable nix flakes (Better tutorial in the ksu_daq repo)
  • install qemu-user-static qemu-user-binfmt qemu-user curl git package then in /etc/nix/nix.conf add: extra-platforms = aarch64-linux arm-linux trusted-users = root <your-user-here> and restart nix-daemon.service

• to build the flake defined image: nix build .#images.rpi --system aarch64-linux

typical workflow:

1. build with either
   • nix build .#images.rpi_top --system aarch64-linux
2. nix-copy-closure --to [email protected] result/ (the output of this will have store path as part of output to switch to)
3. ssh [email protected] (password is nixos)
4. sudo /nix/store/<hash-from-step-2>/bin/switch-to-configuration switch
5. profit
