Don't be afraid I don't want to start a flameware about init systems. I'm trying to understand. It's plaisant, man-pages are well done.

I was tired to switch all the time between distributions for an init system and a package manager. Software are more or less the same between distros. All the need I have and I'm a newbie is source code!

Yes and I realize that people can make flameware about "init system". It's like vi vs emacs. You need to study all.

This is a list of systemd free distributions.

2021 list of “healthy” hardcore distros in alphabetical order

Obarun Linux –> obarun.org (the most extensive distribution that meets the criteria)
Kiss Linux –> kisslinux.org (New and even more promising – independent from community influence)
Kwort Linux –> kwort.org
Sabotage Linux –> sabotage-linux (most inspiring commitments and goals)
Oasis linux –> oasislinux/oasis
Zandra linux –> zandra.org
Mutiny linux –> mutiny.red
Glaucus linux –> glaucuslinux.org
Mere Linux —> merelinux.org (alpha project – active again Musl + pacman )
Iglunix Linux —> https://github.com/iglunix/iglunix/releases, https://iglunix.xyz. (musl busybox no-gnu + alt kernels + wayland NoX)
Chimera Linux —> chimera-linux.org (hard to tell apart from Iglunix)
CarbsLinux —> carbslinux.org (Kiss fork with CPT pkg manager sinit/runit/busybox )
Gobo Linux —> gobolinux.org (Alternative filesystem structure source based glibc)
Venom Linux —> venomlinux.org (forked from LFS glibc now with runit )

It's not fsf in the sense... But I'll become crazy. Stick with trisquel. All I need is a derivation of the GNU operating system.

You copied the 2021 "hardcore list" from the sysdfree website. It's important to note that those writers are a bunch of ultra-purists who are more interested in avoiding a long list of software than they are of recommending actual workable distros. Most of the "distros" on that list either are not an actual working distro, or would be nearly impossible for average users to get installed.

For example, the home page of Chimera Linux currently states, "It does not yet include a kernel or an init system, so it cannot boot yet."

Mutiny.red: "No bootable system yet, this OS mostly exists as a pile of documents and some broken chroots for now."

Sabotage: "Bootstrap your own Sabotage system from source"

Glaucus: "This release is by no means stable and shouldn't be used for production use, it's only here to show that the project is still alive and kicking."

Mere: "Mere’s usability has been low, as ideas and concepts took priority in development over usability. So now, to build some adoption, the project is re-focusing efforts to release a stable and usable first version."

iglunux: "This is a pre-release and isn't meant for use in production. This is meant for people to experiment with Iglunix and try out the system for fun. Installing is a pain and we haven't got any documentation on that yet so have fun :^)." And "In order to boot you may need to add a /dev directory."

Carbs: "Kernel isn't managed under the main repositories, even though you could package one for your personal use. Here is an example kernel package, which you will need to reconfigure for your specific setup if you want to make use of it. "

Oasis installation: "Build/obtain a kernel. By convention, install it at /boot/linux."

Sabotage: "Since our time is limited, some non-core packages that lack a maintainer and we consider of low importance will be updated (upstream URL) without a build test and marked as [untested] in the commit message. Those packages may or may not build. If you find a build error in such a package feel free to report the error or even better, fix it, make a PR and claim maintainership."

Obarun may be the easiest on that list to install. I've tried several times to install it, and was finally successful in my most recent attempt.

If all a user wanted to avoid was systemd, but still have an easy to install distro, the list would be:

FSF-approved:
Parabola openrc version
Hyperbola (not easy to install, but there's pretty good documentation)

FSF-not-approved:
Devuan (easy to install)
antiX (easiest non-systemd distro to install)
Artix (easy to install)
Void
Slackware (not the easiest to install, but there's plenty of documentation)

GNU guix works fine also. I think I have moved to a step where I don't care a lot about the distro. I switch all the time between trisquel and guix and use the same software on both.

You have systemd https://systemd.io/

and on another you have shepherd https://www.gnu.org/software/shepherd/

They all have good documentation. It's not bad after all.

Unfortunately, like so many "debates", the one around systemd seems to have been dominated by an army of ideologues with no interest in context or nuance. Despite the fact that- to me- the concerns around systemd do seem valid, the world wasn't going to be destroyed and software freedom continues as it has always. For most people it is a perfectly acceptable init.

I agree, there's too much polarization around this subject.

Theres trisquel and pureos

but its nigh impossible or difficult

Runit is my favorite, very lightweight more than any other init system, though it is harder than Openrc. It apparently has extremely fast boot and poweroff times.

s6 never used, but I hear its a lightweight way to replace systemd without losing most functionality, still bloated more than other init systems, but hey its possible it could help crush systemd in the future if it does everything systemd does with less of its vulnerabilities and maybe it can be as light as openrc's later versions. Who knows eh?

openrc is simple very much so, but the later versions seem to be getting more bloated, thus its like s6 in some ways, though probably easier for most people.

I think the reason systemd is polarized was because its never been fully audited and breaks so much from the design of simplicity. Also, it is extremely large code base. Like 1 million lines of code or so? I don't know how anyone can find and fix the vulnerabilities with that insane level of creep.

Even s6 and openrc and runit combined aren't that huge.

That being said, debian was right to ditch sysvinit in the past, but they also shouldve looked at openrc, runit, s6 and actually taken them seriously. They are all much more simple to use, to start services, etc...

It still puzzles me that was the path they took, aka to go full on systemd. I heard on debian 11 they decided to allow non-systemd init systems again.

Which is a huge improvement. My two cents

Apparently- I may very well be wrong- Debian's decision was influenced by GNOME already integrating it, which is it at least understandable. If that is indeed the case, however, it's an extremely worrying indication of the sheer influence the corporatist open source philosophy has in the free software community.

I am not sure, research would be needed to know for sure.

Its possible I suppose. I don't know why Gnome is so important that people would need to support it though at the cost of needing something like systemd though.

Not talking about now, but the past.

It just seems like a silly design to me.

Idk... that's just me though.

At least they are rethinking their design if that's the case though.

Which is an improvement.
