Why don't we just fork systemd and remove unneccessary bloat?
Why don't we fork systemd instead? Let's just remove unneccessary parts. Can't we do that? Wouldn't it be better? Or worse?

systemd is the absolute opposite of basic Linux philosophy.
ie: Write programs that do one thing and do it well.

Re: Why don't we just fork systemd and remove unneccessary bloat?
Gday
This is what I don't understand
Why cant the community fork or pull soyd/dbus/avachi from opensource programs?
Why cant we fork stuff like
Hexchat
Smplayer
Mumble
LibreWolf
without soyd/bloat/centralisation/etc ?
Or do what the International Subversives do
* join a project
* inject their changes
* kick out the original group
* take over the project
Even if the community has to res a bunch of old abandoned stuff like leafpad and other stuff
that's been ditched by { THEM }
Does the soydless community even have a plan of action to go ahead ?

There are talkers and doers. Until you become a doer, silence is the best option. Perhaps you'll find a more appreciative audience elsewhere . . .

Re: Why don't we just fork systemd and remove unneccessary bloat?
thats like saying why dont we just fork gtk and remove the cruft, it takes teams of dedicated people. Devuan was the sane choice by forking debian and removing systemd in favour of a tried and true init system, sysvinit.

Re: Why don't we just fork systemd and remove unneccessary bloat?
I use Devuan because it's what Debian used to be. 
If it doesn't suit you, try a different distro, that's the beauty of Linux, choice.

see it is quite comprehensive :-)
Even if the various components are all enabled (as they are for most distributions) there's still no need to use them — other programs can be substituted in instead, as per the UNIX Philosophy.
But it is still trying to do more than what an init system needs to do and programs are being built around it as hard dependencies, it has surpassed being just an init system as you have pointed out here, compared to System V. Gentoo has a nice wiki on this subject worth a read: https://wiki.gentoo.org/wiki/Hard_depen … on_systemd

The systemd team are developing an entire suite of utilities to control a Linux system. Those utilities do not have to be used. For example it is perfectly possible to boot Debian with systemd as PID1 and then hand over to runit for the service management and from that point on avoid any systemd tools:
https://packages.debian.org/bullseye/runit-run
Having the same team develop both the init system and user space utilities is standard practice in true UNIX® systems.

Having the same team go against unix philosophy is quite the conundrum don't you think? Why was Devuan created ?
There is nothing simple, short, clear, modular, and extensible about systemd in my opinion.

Re: Why don't we just fork systemd and remove unneccessary bloat?
I would agree with it not being simple, short or clear but systemd is certainly modular:
archie:~$ systemd-#<tab>
systemd-analyze systemd-machine-id-setup
systemd-ask-password systemd-mount
systemd-cat systemd-notify
systemd-cgls systemd-nspawn
systemd-cgtop systemd-path
systemd-creds systemd-repart
systemd-cryptenroll systemd-resolve
systemd-delta systemd-run
systemd-detect-virt systemd-socket-activate
systemd-dissect systemd-stdio-bridge
systemd-escape systemd-sysext
systemd-firstboot systemd-sysusers
systemd-hwdb systemd-tmpfiles
systemd-id128 systemd-tty-ask-password-agent
systemd-inhibit systemd-umount^ They're all separate tools, most of which can be disabled at compile time, and almost all of them are optional.
In my Arch box I'm not using systemd-networkd but I am using systemd-resolved. I don't use systemd-homed or machinectl (which is actually packaged separately in Debian), nor am I forced to use most other components.
In my Alpine box I'm using gummiboot as a bootloader and that is created from the systemd-boot codebase (after patching to work under musl libc) so the modularity is also portable :-)

Done in a hurry to fix build with latest gnu-efi, this project is dead and was absorbed into systemd

Even if it could be "fully removed" from a Debian system and replaced with an init of your choosing, that ship has sailed a long time ago...

Re: Why don't we just fork systemd and remove unneccessary bloat?
can't wait to have my home directory managed by systemd-homed.
homectl create devuan --storage=luks
simply share your .identity folder between divices and your home directory becomes a modular transferable mount space. This is solving all sorts of problems..
I can't imagine a world where systemd has solved a single problem all it's done is just ended up making things unnecessarily more convoluted.
