From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I am a Linux user, but I don't really know how most things work, even after years of casual use on my Main, I just started getting into Devuan and wondered then, what exacly does systemd do that most distros have it? What even is init freedom? And why should I care?

I had to battle with the fucking initd and upstard before systemd. Those stupid headers of the scripts in /etc/init.d/ we wonderfully undocumented, didn't have syntax checks, depended on a bunch of other shell scripts that didn't have any damn comments in them.

systemd was going to happen sooner or later because nobody was going to put up with that bullshit forever.

Those people arguing about "do one thing right" blablabla don't care about principles, they care about superiority. They want to feel like they're the minority who can do stuff so that in forums they can be toxic and respond with "RTFM" or "LMGTFY". They don't want it easier and more functional, they want it hard so that they can gatekeep.
Like a bunch of Catholics: I experienced pain, so you have to too!

systemd can containerize services! To do that kind of stuff with initd, you'd have to know how create process-, user-, and network namespaces, and a bunch of other stuff.

It's especially funny because systemd isn't one program any more than GNU is. It's a project. systemd-initd handles init. systemd-journald handles journal logs. systemd-resolved handles DNS resolution. Etc. Each systemd daemon has one area of responsibility!
