Sometimes you want the random number sequence to be repeatable. For
example, when debugging a program whose behavior depends on the random
number sequence, it is helpful to get the same behavior in each
program run. To make the sequence repeat, execute (random "").
This sets the seed to a constant value for your particular Emacs
executable (though it may differ for other Emacs builds). You can use
other strings to choose various seed values.

GNU Emacs Lisp Reference Manual: Random Numbersthe random function always generates the same
sequence of numbers. By default, Emacs initializes the random seed at
startup, in such a way that the sequence of values of random
(with overwhelming likelihood) differs in each Emacs run.

Function: random &optional limit This function returns a pseudo-random integer. Repeated calls return a
series of pseudo-random integers.
