 Posted: Sun Apr 28, 2024 9:25 am Post subject: Moving away from systemd |
 |
|
In the last few days I've learned and realized a few things about systemd I personally don't like. From personal preferences to real dangers, I'm not going to discuss them here, because I don't want this thread to be pro vs anti systemd. That's why I'm considering moving away from it.
I've found a few threads here and on reddit and what I think should work is just selecting a non-systemd profile and doing a full world update from a chroot and then figuring it out on the go. I think this should be enough to get me booted in OpenRC, given that all my kernels are both systemd and OpenRC enabled.
Also I'm not a big fan of backups. They cause too few troubles :) With a bootable drive with LiveGUI or an installation CD, I should be fine with whatever it happens, including going back to systemd.
Any thoughts?
EDIT: I can't believe after so many times of reminding users to post their emerge --info, I forgot to do it:

logrusx,
A long time ago you used to be able to install both OperRC and systemd.
Choosing one or the other was a kernel command line option, so it was two boot loader menu entries.
I don't know if thats still possible.

Thank you, I saw that in the other thread I found on the forums.

It's not possible for Gnome users. I guess it is still possible for users who do not need elogind, but it's more work. Thank you for the question, while I was thinking about it I kind of learned something new... or made new connections between things I already knew.

Aside from rebuilding all packages that were installed with the systemd USE flag set, and making sure that the elogind USE flag is set for those that require some logind provider, the challenges would be convincing Portage to install the packages that provide conflicting files:
- sys-apps/systemd[sysv-utils] vs sys-apps/openrc[sysvinit], for shutdown, poweroff, reboot, etc.
- sys-apps/systemd vs sys-apps/systemd-utils[udev, tmpfiles], for systemd-udev, libudev and systemd-tmpfiles.
Then, if you have a systemd version that removed the support for nonmerged /usr, you need to migrate to a merged /usr OpenRC profile... so migration from 17.1 to 23.0 must be done first, if not done already, to have such profiles available.
That's what I can think of off the top of my head.

I don't think so. It might have been possible in the early days of systemd, but now, I believe systemd and nonsystemd GNU/Linux variants have become too incompatible to just switch back and forth with an init= kernel parameter.

After moving off of default/linux/amd64/23.0/desktop/gnome/systemd:

That's it. Looks very good, I still haven't decided on giving it a try. Still waiting if something else comes to my mind or, for reasons not to do it.

If you can install openrc while still keeping systemd, it shouldn't be as complicated as one might assume.
You'll probably have to juggle around with some use flags after profile switch (be sure to first switch fully to 23 profile if you haven't already).
Back in 2017, I did the same switch.
If you cannot have both, openrc and systemd installed at the same time, you'll probably need to boot from some live medium at some point.

| some packages (example: thinkfan) do not have systemd/elogin flag, but they manage init files on their own. Switching profile does not trigger their rebuild, which is needed to generate proper init files. No one can know all ebuilds with this broken behavior, and world update with empty tree is needed. |

I don't intend to keep systemd, the above was just a comment in response to Hu's comment. And yes, I think I need to boot from a live medium, I can't imagine doing it on a live system. After all I'm removing core parts of the system and then I have to shut it down properly. I don't think that'll go 100% safely.

Some time ago when I was writing an ebuild which included systemd support, I was told in #gentoo-dev-help it's better to ship both systemd unif files and rc files and not worry about that. I hope most of the ebuilds I have follow the same practice. Also I don't have many running services and I guess it'll be easy to just figure it out when I boot. Emerging the whole world is just too slow, even with the binhost repo. When I migrated to 23.0 it took me more than 8 hours. Some small packages even seemed to take more time than they would have if they were built from source.

My point was that if you can have both installed, then rebooting from the old init to new init system is easy and can be done without using any live environment.
Then, after first boot with the new init system, depclean the old init (systemd).

At a first glance it seems it may very well be more headache than going back to systemd if the migration fails. Maybe if I didn't have Gnome, but I don't feel comfortable depcleaning it... yet. Yes, Gnome is on the list of things I'm starting to really dislike.
On a side note, looking at the link you provided, I need to take care of the dns and dhcp too. Now I've let systemd to manage the dns and networkmanager to manage the ip address if I'm not wrong.

1: If possible due it from a "live-usb" environment by chrooting. You'll get into trouble when replacing the init system, dbus and so on on a live running system.
2: Make sure to configure critical services before booting.
3: Take a note of services you've customized and edit the same openrc services likewise.
4: Make sure you aren't running packages that hard-depend on systemd, and remove them first if yes.
It's pretty easy jumping between systemd and openrc, but without any planning you may find yourself panicing if something goes wrong. |

Of course. It doesn't seem feasible to both install OpenRC and keep systemd given I'm a Gnome user.
| Juippisi wrote: | | 2: Make sure to configure critical services before booting. |
What are some of those? I haven't used OpenRC (and Linux at all) since ~2010 and then I cam back to Linux straight to systemd. I don't remember much. The other two points are of no concern in my case.

That's almost like a Gentoo meme. :')
Like the time when I wrote a script, but didn't put proper checks into it and it ran | Code: | | rm -fr "${NULL_VARIABLE}/*" |
Next step was: "Oh well... I better reread foremost man page...".
Eventually I survived.
How's your init transition? Already done? :)

I haven't started yet. Not feeling adventurous right now. Otherwise I have no important job to do and now may be the right moment, but I'm hesitating until I gain better clarity of what should be done. It turns out systemd is doing a few jobs which are otherwise done by something else and I'm sitting on that thought for a while to see if something important will come out of it.
I'll check the openrc part of the handbook to gain more clarity.

Basically fstab and mounting of encrypted partitions if you have those, dbus, logind, networking, display-manager. Stuff that allow you to login to your desktop and prevents you from figuring stuff out in the TTY. Networking is also easy if you use a generic dhcp client, but still differently handled compared to systemd. You'll most likely figure rather fast what you missed when you log in the first time :) |

Fstab is necessary regardless of the init system or am I wrong? I just realized I'm using NetworkManager, so networking should not be an issue. Aside from pipeiwre I think I haven't modified any other systemd unit, so that should be straight forward too. Dbus, logind, display manager should be easy. One thing I wonder about is how to convert logs from systemd journal. Last night I reviewed the handbook which includes the links you posted. I was surprised that the handbook didn't end where I thought it did and there was a lot of other stuff.
I think I'm ready to attempt this.

What does that even mean?I don't need to change bootloader. If this is a joke, please refrain from trying to make jokes here. Gentoo Chat or #gentoo-chat is a more appropriate place for that.

Having had some time to think about it and even been on the verge of starting it, I've gained much more clarity of what needs to be done but as well I have realized If I migrate now, that won't prevent what I'm afraid of happening to systemd affect me either way. So I've decided to not move forward at this point. I'll think about it when it happens or I'll migrate if more pressing reasons to do so arise.

Edit: When I switched, it was probably easier because I had already been running openrc first, then switched to systemd, then switched back to openrc... so I probably skipped many steps that would need to be done if one had never used openrc on the same system.
I switched back from systemd to openrc a week or two ago with just one reboot (the actually reboot to switch), no chroot, done live. I needed to use my computer's reset button to reboot because of course at the time of the reboot, systemd was no longer on my computer, so it might not have been the cleanest reboot, but I closed and stopped as much as possible first.
I'm sorry that I didn't record the exact steps, though. It basically involved switching to a non-systemd profile and running 'emerge -puvDN --with-bdeps=y @world", then removing anything clearly systemd-related that caused a hard block. There were only three or four packages. It might have been just systemd and gentoo-systemd-integration. Once that was done, I ran the actual update and rebooted. |

That's why it should be done in a chroot because otherwise you're facing the risk of losing data.

Switch to OpenRC is no big problem: https://forums.gentoo.org/viewtopic-t-1164802-highlight-.html
Check the merged-usr thing first for select the right 23 profile. Test with an image from your system in a vm.
But from the user's point of view, my Gentoo now works exactly as it did before. OpenRC doesn't offer any advantages, the computer boot is even slightly slower.
But now I'm one of the cool people who don't use SystemD and can rant about systemd.  But nobody cares about that either.  |
