I fully get this. Though ideology is a pleasant game for mind though not useful if it cannot be practically implemented. How I see it, it is very easy to set random seed by providing some automatically generated, random string to `random', such as those from the system's /proc directory. random is a built-in function in ‘C source code’. (random &optional LIMIT) Return a pseudo-random integer. By default, return a fixnum; all fixnums are equally likely. With positive integer LIMIT, return random integer in interval [0,LIMIT). With argument t, set the random number seed from the system’s entropy pool if available, otherwise from less-random volatile data such as the time. With a string argument, set the seed based on the string’s contents. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
