++iopen Makes an invisible pseudo-directory called
++ __iopen__ available in the root directory
++ 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
++ permissions on the file itself is
++ world-readable.
++
+ grpquota,noquota,quota,usrquota Quota options are silently ignored by ext2.
