Hi,
I've wondered why noone (to my knowledge) has suggested to write
a tool similar to fsirand. Fsirand randomizes all inode numbers
on a system, which makes guessing file handles a little harder.
Of course the randomization used in such a tool should be
"really random", so that we don't end up with the same problem
as SunOS: the random element used in fsirand wasn't random enough.
Comments anyone?
Peter
