The idea as far as I can tell is that it's responsible for too many things and gives a massive point of failure.
It isn't though, systemd is broken into smaller parts.
Indeed, the Unix philosophy was do one thing and do it well. ls just list directory’s and files it’s not a network manager too. Systemd crams a lot of extra shit into an init.d/rc.
I still prefer the old system-v/openRC setup or BSD’s setup. It’s simple does 1 job and does it well. But I can work with systemd just fine in creating scripts these days and it does have some nice features like user startup scripts baked into it and podman integrates very nicely with it.
It's also "infectious" software. The way systemd positions itself on the system, it can make it more difficult for software to be written in an agnostic way. This isn't all software, and is often more of a complaint by lower level software, like desktop environments.
https://catfox.life/2024/01/05/systemd-through-the-eyes-of-a-musl-distribution-maintainer/ This isn't a terrible summary of some of the aspects of it.
Another aspect is that when it was first developed, the lead on the project was exceptionally hostile to anyone who didn't immediately agree that systemd definitely should take over most of the system, often criticizing people who pointed out bugs or questionable design decisions as being afraid of change or relics of the past.
It's more of a social reason, but if people feel like the developer of a tool they're forced to use doesn't even respect their concerns, they're going to start rejecting the tool.
the develope receive a fuck ton of hate too, and he keep the project going, against every one unix-way haters
Well, I don't give him too much credit for that given that it was his day job, not some passion project.
Most of the hate towards him was because he took an abrasive stance against anyone who disagreed with him, or pointed out bugs.
What do you expect from an init system? It's like saying my cpu is infectious because my computer depends on it
It's that it also decided to take over log management, event management, networking, DNS resolution, etc, etc.
If it were just an init system that would be perfectly portable. People were able to write software that way with sysv for years.
It's that in order to do certain low level tasks on a systemd system, you need to integrate with systemd, not just "be started by it". Now if a distro wants that piece of software, it needs to use systemd, and other pieces of software that want to be on that distro need to implement integration with systemd.
A dependency isn't infectious, but a dependency you can't easily swap out is, particularly if it's positioned near the base of a dependency tree.
Almost all of my software can run on x86 or arm without any issues beyond changing compiler targets. It's closer to how it's tricky to port software between Mac and Linux, or Linux and BSD. Targeting one platform entails significant, potentially prohibitive, effort to support another, despite them all being ostensibly compatible unix like systems.
Bro I’m with you on this but the systemd bots will just keep arguing with and downvoting you. Don’t bother.
and this is a bad thing? the distro can choose to not use it, but because every systemd distro uses it, it's a 1000x easier to implement it without needing to put a fuck tons of if-else's for every distro
No, not everyone thinks it's a bad thing. It is, however, infectious, which is a reason some people don't like it.
Knowing why people dislike something isn't the same as thinking it's the worst thing ever, and liking something doesn't mean you can't acknowledge it's defects.
I think it's a net benefit, but that it would be better if they had limited the scope of the project a bit, rather than trying to put everything in the unit system.
and what's the problem?, it's not like everything is in the same binary or it's a monstrosity that can't be used without using every single feature, it's a project that just has different programs under the same project name, because no one wanted todo theoe programs
That’s why I personally try very hard to only rely on POSIX stuff, even when it’s massively inconvenient. The only thing I haven’t gotten around to replacing yet is GNU make.
I think the init system is the best part of systemd. It is sooo easy to use. You don't have to write the same complicated shell script for your software like everyone else. You just give systemd the path to your executable and that's basically it. It does the rest and you don't have to worry about PID files or forking the actual software. Systemd basically runs it like you did while developing it.
I think what people don't like are all the other parts of systemd that seem to be tightly coupled. I don't know if it is even possible to run just the systemd init without any other systemd package.
The last time I got angry at systemd was when resolvd did some DNS shit I did not approve of.
I may be wrong but I believe that all of the systemd programs are decoupled. You can run the systemd init system without any resolved or networkd. They just happen to be used by default on a lot of distros.
I expect it to not run a stop job for 90 seconds by default every time I want to quickly shut down my laptop. /s
it doesn't run a job it waits for your jobs to end. You can set the default want time. Its the same thing on windows that asks programs to close before shutting down. If a critical application got stuck systemd has nothing to do with it
I know what it is. But it literally says "A stop job is running" and since english is not my first language, I had no good idea how to better express the technicalities of it in a short sentence.
As for it having nothing to do with systemd:
I am dual booting arch and artix, because I am currently in the middle of transitioning. I have the exact same packages on both installs (+ some extra openrc packages on artix).
About 30% of the shutdowns on arch do the stop job thing. It happens randomly without any changes being done by me between the sessions.
0% of the shutdowns on artix take more than 5 seconds.
I know that I can configure it. But why is 90 seconds a default? It is utterly unreasonable. You cite windows doing it, but compare it instead to mac, which has extremely fast powerups and shutdowns.
And back to the technicalities, openrc doesn't say "a stop job is running", so who runs the stop job if not systemd?
The question you should be asking is what's wrong with that job which is causing it to run for long enough that the timeout has to kill it.
Systemd isn't the problem here, all it's doing is making it easy to find out what process is slowing down your shutdown, and making sure it doesn't stall forever
I will not debug 3rd party apps. I don't even want to think about my OS nor ask any questions about it. I want to use a PC and do my job. That includes it shutting down asap when I need it to shut down asap.
systemd default - shutdown not always asap
openrc default - shutdown always asap
whatever the heck macs init system is - shutdown always asap
It may be not the "fault" of systemd, but neither does it do anything helpful to align itself with my needs.
The default is as long as it is because most people value not losing data, or avoiding corruption, or generally preserving the proper functioning of software on their machine, over 90 seconds during which they could simply walk away.
Especially when those 90 seconds only even come up when something isn't right.
If you feel that strongly that you'd rather let something malfunction, then you're entirely at liberty to change the configuration. You don't have to accept the design decisions of the package maintainers if you really want to do something differently.
Also, if you're that set against investigating why your system isn't behaving the way you expect, then what the hell are you doing running arch? Half the point of that distro is that you get the bleeding edge of everything, and you're expected to maintain your own damn system
If an app didn't manage to shut down in 90seconds, it is probably hanging and there will be "DaTa LoSs" no matter if you kill it after 2 seconds or after 90.
Been running arch for over 5 years now.
I track all my hours and for arch maintenance I've spent a grand total of ~41 hours (desktop + laptop and including sitting there and staring at the screen while an update is running). The top three longest sessions were:
|
It's about 8.2 hours per year (or ~10minutes per week) which is less than I had to spend on windows maintenance (~22h/y afair, about half of that time was manually updating apps by going to their website and downloading a newer version).
Ubuntu also faired worse for me with two weekends of maintenance in a year (~32h), because I need the bleeding edge and some weird ass packages for work and it resulted in a frankenstein of PPAs and self built shit, which completely broke on every release upgrade.
Can you expand a bit on that? I thought it didn't matter if you deleted parent snapshots because the extents required by the child would still be there.
Honestly, I have no idea why it went wrong or why it let me do that. Also my memory is a bit fuzzy since it's been a while, but as best I can remember what I did step by step:
Gotcha. That must have been a kernel bug (or hardware error), none of the userspace utilities could cause it unless they were trying to manipulate the block device directly, which would be really dumb. It's possible it wasn't even related to the subvolume manipulation.
You can shut down any computer in ten seconds by holding the power button.
The best solution!
Man, wait until these people hear about the filesystem and kernel.
In some ways I think the filesystem is philosophically the exact opposite of systemd
I can boot my system with an ext4 root, with a btrfs /home...or vice versa. Or add some ZFS, or whatever. The filesystem is (with the exception of some special backup schemes) largely independent of the rest of the system, despite being of core importance.
On the other hand, I can't change my init system (i.e., systemd) without serious, serious work.
hurd "exists"
Does it ? I thought it was never completed !
On the other hand, if you want a microkernel that does exist, there’s Mach. But I don’t think you can replace Linux with it 😆
Yeah, there's a Debian implementation of GNU/hurd. Debian recommend you run it in a VM
I won't bother. Sounds like hurd work.
Hurd is supposed to work with GNU mach afaik
It's been two years away for the last 30 years.
That's GNU/Hurd thank you
yes mr stallman
The very existence of a defined kernel is an insult to the Linux philosophy
The Linux kernel (the part that gives Linux the name) is antithetical to Linux philosophy? I could understand it being contrary to GNU philosophy
