The argument is basically that it does too much and as the motto of Unix was basically "make it do 1 thing and that very well", systemd goes against that idea.
You might think it is silly because what is the issue with it doing many things. Arguably, it harms customization and adaptability, as you can't run only 2/3 of systemd with 1/3 being replaced with that super specific optimisation for your specific use case. Additional, again arguably, it apparently makes it harder to make it secure as it has a bigger attack surface.
Sustemd is modular though, you don't have to use every subsystem. The base init system and service manager is very comprehensive for sure.
And funnily enough, the kernel doesn't follow the unix philosophy either as far as I know.
I have heard that before in a joke setting, I would love to hear genuine arguments for and against it.
The debate is as old as Linux itself, and well documented.
It doesn't seem to be a debate. "Microkernels are better" "yes but I don't have the time for it" but thanks
At a high level, microkernels push as much as possible into userspace, and monolithic kernels keep drivers in kernel space
There are arguments for each e.g. a buggy driver can’t write into the memory space of another driver as easily in a micro kernel, however it’s running in the same security level as userspace code. People will make arguments for both sides of which is more secure
Monolithic kernels also tended to be more performant at the time, as you didn’t have to context switch between ring 0 and ring 1 in the CPU to perform driver calls - we also regularly share memory directly between drivers
These days pretty much all kernels have moved to a hybrid kernel, as neither a truly monolithic kernel nor a truly micro kernel works outside of theoretical debates
I feel like the people who complain about systemd have never tried to mess with sysVinit scripts before
6+ years ago, I was trying to configure a touchscreen HAT for a raspberry pi, and dicking with the init.rc script was a massive pain
The alternatives to systemd isn't init.d or some other legacy init systems. I use runit, pretty easy to understand and use. Stop being lazy dude
Hi am noob why systemd bad? I use Debian, is fucked?
Honestly I've been hearing about this for a while now but never bothered to check, I'm too lazy for that.
It's not inherently bad, it "fails" the Unix Philosophy of "Do one thing and do it well" but since Linux's kernel is:
- Unix-like, not Unix
- Fails this philosophy, as it does more than one thing but does all of it pretty well
- systemd is just a bundle of tools that do one thing and do it well under one package, like Linux's kernel
It used to be a mess, but that's solved. The biggest reason to avoid systemd is mainly user preference, not anything malicious. 90% of current distros use systemd as its easier for the maintainers and package programmers to build for the general than each package and each distro having their own methods of how to do an init system and other tasks.
How Debian and Arch and Gentoo and Slackware and other big distros worked was different, and the maintainers of those packages had to know "Debian's way" and not a general way that most places accept. Systemd actually solved the Too Many Standards! issue.
I've never really seen a big argument against systemd, but maybe I've just not heard it.
back when you had an init system and you got it just the way you wanted it, you would be pissed that you had to move to systemd
now its there when you install and it is stable so it isn't a big deal. But old beards hate change.
Old beards built linux and everything around, have some respect.
anyone ever seen a goldwing? it was supposed to be a motorcycle but for some reason has a fridge, microwave and what not added.
it is still a motorcycle. you can ride it. it starts right away and has all sorts of extra functions.
and now look at it. it is an ugly piece of engineering that only the weirdest of people like.
dont ride a goldwing. dont use systemd.
No clue about motorcycles but those things look neat and win awards. I want one now. Thanks for turning me on to this neat bike.
yeah sure. enjoy that and some systemd. everyone likes different things.
What are you talking about? The goldwing has been consistently hailed as one of the best touring motorcycle for almost 40 years. Every long distance rider I've spoken to says the goldwing is their favorite bike for cross country rides, and the ones who have sold theirs for a BMW or Harley touring bike have expressed regrets about changing.
Just because something has a lot of features, doesn't mean it's bad.
where i live ppl laugh about goldwing riders. it is considered the idiots bike: https://avida.cs.wright.edu/personal/wischgol/fsr/Guenther/Goldwing.html
..just one example.
google suggest in my country autocompletes goldwing with "mikrowelle" (microwave).
maybe we just have a different taste.
