Whew, wont lie, I am getting tired and I had to reread that a few times till it clicked.

SystemD… and Linux gaming.

I am far from an expert on systemd and its alternatives, but so far all what I at least think I know is:

SystemD is not as efficient as other paradigms could be,

It could potentially be a massive security vulnerability, or maybe not, or maybe so, or no one seems to agree on this and then everyone starts yelling,

I am reasonably confident that at least currently there are not any existing alternatives to SystemD that allow one to play much less develop basically somewhere between any to most games that involve 3d graphics.

Again, I could be completely wrong about all of this, absolutely beyond my experience and skill set to comment much more than:

A systemd alternative that would allow for modern kinds of multiplayer 3d online games would be really neat, but it seems like it would take a massive amount of effort that is at least nearly certainly beyond my ability to contribute to in any meaningful way.
