>Lennart just keeps adding to systemd and refuses to say when he will finally stop adding to it.
I'm not sure I understand, most projects only stop adding code when development is done. So the answer would probably be "when people stop using it." Are you a distro maintainer? If you want a stable version with fixes backported, you can use this: https://github.com/systemd/systemd-stable
>How many skilled humans on this planet are available to audit those 600k+ lines of systemd code and are actually auditing it? (And how many work for intelligence agencies?)
I'm not sure I understand this either, are you asking how many C programmers there are in the world that are able to perform code review on a C program for Linux, like systemd? And what subset of those C programmers work for intelligence agencies? It might be worth answering those questions, but I'm not sure how that is related to systemd specifically. If you look at the systemd github (or the github for any other big C program), you will see a good number of people already publicly reviewing patches, so you could get started there.
