components

            The standard python `os.makedirs` is insufficient for our
            needs: it will only create directories, and ignores the fact
            that some path components may be symbolic links.

            :param src: The source path in the host file system for which
                        leading components should be created, or the path
                        to an sos_* virtual directory inside the archive.

                        Host paths must be absolute (initial '/'), and
                        sos_* directory paths must be a path relative to
                        the root of the archive.

            :param mode: An optional mode to be used when creating path
                         components.
            :returns: A rewritten destination path in the case that one
                      or more symbolic links in intermediate components
                      of the path have altered the path destination.
