    Flakes solve this problem by ensuring fully hermetic evaluation.
    When you evaluate an output attribute of a particular flake (e.g. the attribute defaultPackage.x86_64-linux of the dwarffs flake),
    Nix disallows access to any files outside that flake or its dependencies.
    It also disallows impure or platform-dependent features such as access to environment variables or the current system type
