> We need to generate a lot of random bytes. It is a good idea to perform some other action (post a news story about systemd, Lennart Poettering, or Ubuntu) during the prime generation; this gives the random number generator a better chance to gain enough entropy.
You just provided another argument against systemd: it ships with its own version of a random number generator, tightly coupled into the init system. Myth 1 demythified!
(The implementation is also pretty bad, there are quite a lot of predictable comments here…)
