Can you tell me a bit about your system? What distribution, what hardware is present in your sytsem (what architecture, what peripherals are attached, etc.)? There's a reason why we made this --- we were declaring the random number pool to be fully intialized before it really was, and that was a potential security concern. It's not as bad as the weakness discovered by Nadia Heninger in 2012. (See https://factorable.net for more details.) However, this is not one of those things where we like to fool around. So I want to understand if this is an issue with a particular hardware configuration, or whether it's just a badly designed Linux init system or embedded setup, or something else. After all, you wouldn't want the NSA spying on all of your network traffic, would you? :-) - Ted
