RDRAND on AMD Ryzen 9 5900X is flakey
Given that rdrand is so flakey across systems, is there a reason why systemd even bothers using it? The comments suggest it&#x27;s only used to generate uuids, which makes me think it&#x27;s not performance sensitive code. If that&#x27;s the case why increase code complexity and expose yourself to hardware flakiness just to save a few miliseconds?
