I can see this as an additional option, but I also feel that we should provide a basic, workable, one; (2) --random-source=/dev/zero will bypass (1), but will defeat the idea of a random shredding; (3) finally -- and more critical, perhaps -- the new default for --iteractions forces *all* three (default) passes to be random. I have been trying to figure a way of getting this done with minimal changes, but have not yet succeeded (well, part of the issue is having the time to dedicate to it). Cheers, ..hggdh..
