Yes, that's what I plan to do in GNU projects like Coreutils and Emacs. Although I don't recommend arc4random, I suppose it was added for source-code compatibility with the BSDs (I wasn't involved in the decision). > is there anyway that glibc can *not* do this, or has that > ship fully sailed It hasn't fully sailed since we haven't done a release. > it's fun to make a random number generator, and so lots > of projects figure out some way to make yet another one somewhere > somehow. That's a bit harsh. Coreutils still has its own random number generator because it needed to be portable to a bunch of platforms and there was no standard. Eventually we'll rip it out but there's no rush. Having written much of that code I can reliably assert that it was not fun.
