Turns out <code>chmod</code> is not part of our build environment either; that's how minimal the low-level derivation environment is! However, before we fix the script in a similar manner, let's observe another important detail: the store path. Compare the build location of this example, and the previous one; the SHAs are different! That is because our derivation has different inputs to the one before, therefore it's built under a different location in the Nix store. And to highlight this, without fixing the script, let's build it again: | Turns out <code>chmod</code> is not part of our build environment either; that's how minimal the low-level derivation environment is!
