Okeeeeeey, so who's is stuck in their ways?
I'm on Guix which doesn't use SystemD. Running on an MSI GS66 Stealth laptop with an Nvidia RTX¹ 3080. I browse the web, develop, run Stable Diffusion on the GPU, game using Steam and Lutris (Chivalry 2 and Diablo 4), Zoom calls for work.
Mainly this just like any other machine.
¹ or whatever the letters are these days.
Before switching to Guix I ran Void Linux for years. It's a very nice, light and quick distribution. The BSD of Linux if you will.
Can very much recommend it.
The things with init systems is as an average user you don't really realize they're there. Whether it's SystemD or something else and I wouldn't worry too much about them.
