Reproduce the hang by running ./dsc with the provided Brew and RunCommandOnSet configuration on macOS; compare it with sudo ./dsh, which makes Homebrew fail as root. Trace the command entry point and sudo password handling, and consider the issue done when the configuration completes without hanging while Homebrew is not run as root.
