➜ secret-operator git:(main) nix-shell error: executing shell '/nix/store/5p86w1968gs5abgqkj9wv5gccxpy253c-bash-interactive-5.3p3/bin/bash': Argument list too longThe buildInputs and nativeBuildInputs lists were constructed by concatMapping over all transitive crate dependencies without deduplication. Since hundreds of crates share the same native build inputs (Rust compiler, linker, pkg-config, etc.), identical store paths were repeated hundreds of times, bloating PATH and other environment variables beyond the kernel's ARG_MAX limit.
Wrapping both lists with pkgs.lib.unique eliminates the duplicates and brings the environment size back within limits.
