Function execute_directories logged in a way that was meaningless without additional context: systemd[1]: No executables found. In execute_strv this was partially rectified by extracting the directory name from one of the directories and using this as the identifier. But the directory name is not always meaningful, and can also be set from an environment variable. Let's simplify things by providing a fixed name that can be used consistently in all log messages. In particular this will make error messages easier to understand if users report just the error without additional context.
