"Under 2.4.x kernels, there is a file type in the result of readdir to
help applications optimize directory traversal.  With usfficiently new
libc compiled against sufficiently new kernel headers, this is exported to
applications.

Several applications, including fileutils use this information.  AFS
asserts that all files are directories.  This sucks, because among
other things it causes rm -rf not to work."
