++iopen                         Makes an invisible pseudo-directory called

++                              of the filesystem.  Allows open-by-inode-
++                              number.  i.e., inode 3145 can be accessed
++                              via /mntpt/__iopen__/3145
++
++iopen_nopriv                  This option makes the iopen directory be
++                              world-readable.  This may be safer since it
++                              allows daemons to run as an unprivileged user,
++                              however it significantly changes the security
++                              model of a Unix filesystem, since previously
++                              all files under a mode 700 directory were not
++                              generally avilable even if the
