This value MUST be an absolute path.

* Windows: one mount destination MUST NOT be nested within another mount (e.g., c:\\foo and c:\\foo\\bar).

On Linux and Solaris, if the directory does not exist, the runtime SHOULD create the directory with mode `0755`.

This specification extends the IEEE standard in that at least one entry is REQUIRED, and that entry is used with the same semantics as `execvp`'s *file*.
