    Description

      PATH_MAX affects the path length of a single pathname, but it is possible to exceed this by eg. creating a subdirectory tree, then cd into it (or use as a subdirectory mountpoint), then create a deep tree below this using a relative pathname.

      So 'lfs fid2path' should not limit its output buffer to PATH_MAX.
