fsirand(1)              (BSD Compatibility Package)              fsirand(1)


   NAME
         fsirand - install random inode generation numbers

   SYNOPSIS
         /usr/ucb/fsirand [ -p ] special

   DESCRIPTION
         fsirand installs random inode generation numbers on all the inodes on
         device special, and also installs a filesystem ID in the superblock.
         This helps increase the security of filesystems exported by NFS.

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

         The -p option prints out the generation numbers for all the inodes,
         but does not change the generation numbers.
