-Like \-uniquelocal, but using /dev/random instead on Linux systems for highest-quality random number generation. On other systems, this option is equal to \-uniquelocal. Note, that reading from /dev/random may take some time. You can speed up this process by delivering random input e.g. by pressing keys or moving the mouse.
