fsirand(1M)                                           fsirand(1M)



     NAME
          fsirand - install random inode generation numbers

     SYNOPSIS
          fsirand [-p] [-Tfile-system-type] special

     DESCRIPTION
          fsirand installs random inode generation numbers on all the
          inodes on device special and also installs a file system ID
          in the superblock.  This helps increase the security of file
          systems exported by the network file system (NFS).

          fsirand must be used only on an unmounted file system that
          has been checked with fsck(1M).  The only exception is that
          it can be used on the root file system in single-user mode,
          if the system is immediately rebooted afterward.

     FLAG OPTIONS
          The following flag options are interpreted by fsirand:

          -p   Print out the generation numbers for all the inodes,
               but do not change the generation numbers.

          -T   Indicate the file-system type, for example 4.2 or 5.2.
               If this option is not present, fsirand attempts to
               determine the file-system type.

     FILES
          /etc/fsirand
