I am pretty new to nix, and I work on a project where postInstall was being used to copy some static assets. I noticed that the build would crash on some machines, usually checking/attempting patchElf on png or js files, so I changed our build to use postFixup. postInstall seems best logically, but I also wonder whether image files, JS files, or CSS files should have any fixup applied to them.

I have used a makefile similarly in the past. I am leaning towards using a bash command with subcommands that correspond to each target in my next project, probably named "go"

I am curious how you would setup backend integration tests in this example.
