Thank you, Callyral. I didn’t know either. But now I’m trying to learn Linux again after 30 years of not touching it, so this is helpful.
If I may ask an additional possibly stupid question (coming from Windows/Mac): as an init system in Linux, after you get past BIOS and POST at power up, is systemd also responsible for the initial OS software boot process (the “bootstrap” or Boot Manager in DOS/Windows) or is that another process altogether?
Or, asked another way, does systemd load the Linux kernel, and if not, what does?
Just so you know, I have no real skin in this game yet; I’m just trying to figure out where systemd starts and stops so that I can follow the [endless] debate, lol.
