     fsirand -- install random inode generation numbers in a filesystem

     fsirand [-F] [-p] [-x constant] special

     fsirand writes random inode generation numbers for all the inodes on device special.  These
     random numbers make the NFS filehandles less predictable, increasing security of exported

     fsirand should be run on a clean and unmounted filesystem.

     The options are as follows:

     -F      Indicates that special is a file system image, rather than a device name.	special
	     will be accessed 'as-is', without requiring that it is a raw character device and
	     without attempting to read a disklabel.

     -p      Print the current inode generation numbers; the filesystem is not modified.

     -x constant
	     Exclusive-or the given constant with the random number used in the generation

     fsirand exits zero on success, non-zero on failure.

     If fsirand receives a SIGINFO signal, statistics on the amount of work completed and esti-
     mated completion time (in minutes:seconds) will be written to the standard error output.
