awesome, I'm going to give this a try... One thing I notice, is this url is just given, without much context: `https://hydra.nixos.org/build/142828023/download/1/nixos-sd-image-21.05pre288297.8eed0e20953-aarch64-linux.img.zst https://hydra.nixos.org/build/142828023/download/1/nixos-sd-...` But I (think I) know enough about nix to know this is an image generated by the build system, and in theory I should be able to browse hydra, to find other images that I could try to burn, I think some info about where that image came from would be super helpful in understanding nix's build system.
