install random inode generation numbers
From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.
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.
