nixos-compatible install process

[silky]

thanks for putting this together; it looks awesome!

unfortunately, the model of downloading binaries and running them is a moderately incompatible with nixos; it would be really nice if there was an alternative way of getting all the dependencies

some ideas:

• add a flake.nix that builds the projects and all the deps
• create a docker image with all the necessary deps so that can be a workaround
• ???

thanks :)

Thanks for the interest! I don't have any expertise with Nix, but we'd be happy to accept a PR setting up the Nix flake.

thanks for being open to it!

i've been trying with cargo2nix but getting some errors that will probably take a nix rust expert to resolve 🥲

for anyone inspired to look into it, the errors were:

• it seems like cargo2nix/nix doesn't like submodules
• i needed a sad override for openssl

          packageOverrides = pkgs: pkgs.rustBuilder.overrides.all ++ [
            (pkgs.rustBuilder.rustLib.makeOverride {
                name = "openssl-sys";
                overrideAttrs = drv: {
                  OPENSSL_NO_VENDOR = 1;
                };
            })
          ];

• the actual error preventing the cargo2nix flake.nix example from working is:

and i have no idea how to fix that.
