    That’s a pretty extensive post, nicely done. I have one nit with most setups like this.

    With the way the RPi boots by default you unfortunately won’t get a bootloader with the ability to rollback to a previous generation. There are multiple projects providing a much better boot experience on the 64-bit Raspberry Pis (and other ARM devices). They allow the use of an EFI interface to boot and install the default ARM installer ISO e.g. via USB.

      Thank you. This is valuable input. I was happy to get the thing running at all and hearing others were having issues I wanted to record my steps. I can’t promise I’ll be expanding on the documentation any time soon as I’ve yet to find a purpose for it in to continue tinkering.

      I also manage my Pi 3B with NixOS! At first I built everything directly on the Pi, which was very painful, then I went through NixOps first (which I documented) and now Colmena, and I haven’t migrated to flakes yet. Here’s my configuration if you wanna take a look.

        FWIW, Samba cross-compilation has be fixed as of this commit. If you bump your Nixpkgs revision, it should work.

          Thank you! This is great to hear! I’m just whinging it, basically. First I need to find something to use this box for though 😂

            Or, as always, you can add https://github.com/NixOS/nixpkgs/commit/118e531c2d1b80389a69fce0a24c0258fff2e5a7.patch to your patches=[] for nixpkgs!
