- * Quoth POSIX: The size of sun_path has intentionally been left
- * undefined. This is because different implementations use different
- * sizes. For example, 4.3 BSD uses a size of 108, and 4.4 BSD uses a
- * size of 104. Since most implementations originate from BSD
- * versions, the size is typically in the range 92 to 108.
