If that is wrong… > please by all means, please teach me, how it would be. getrandom() will never "consume entropy" in a way that will block any users of getrandom(). If you don't have enough collected entropy to seed the rng, getrandom() will block. If you do, getrandom() will generate as many numbers as you ask it to, even if no more entropy is ever collected by the system. So it doesn't matter how many clients you have calling getrandom() in the boot process - either there'll be enough entropy available to satisfy all of them, or there'll be too little to satisfy any of them. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx
