With Trixie, comes changes…

As someone who has been running Debian servers for about a decade, one thing I’ve always appreciated is that if you didn’t like a core component, you could swap it out. That used to include the init system. Whether you preferred sysvinit, OpenRC, or runit, Debian gave you the tools to do it.

With Debian 13 Trixie, that is basically over.

What Changed

To be clear, Debian as defaulted to systemd since Jessie; we’re not talking about that. We’re talking about the OPTION to use another system instead. On Bookworm and earlier, moving away from systemd was simple:

apt install sysvinit-core
reboot

You might clean up a few services or install orphan-sysvinit-scripts, but it worked.

In Trixie, too many core packages now assume systemd is there. Udev is the most obvious example. During upgrades, it will pull in systemd even if you’re trying to stay init-free. Other essential packages have dropped their init scripts or unit files for anything else. If you boot without systemd, critical services will fail. The choice exists in theory, but it’s fragile and unsupported in practice.

Why It Is Happening Now??

This isn’t random. Version 13 tightens dependency chains across the core system. Packages such as udev, dbus, logind, and many desktop or network management components are systemd-aware by default. In previous releases, these dependencies were optional or provided fallbacks. In Trixie, the fallback paths are gone or broken. Swapping init now can silently break critical parts of the system.

For Some, Devuan May Finally Make a Lot of Sense

I never really understood why Devuan existed. On Jessie, Buster, Bullseye, and Bookworm, one could do a base install, install their init of choice, reboot, and purge systemd. Devuan always seemed like a convenience for users who wanted to skip that step.

Now, changing init is a literal nightmare. The system doesn’t allow it. You’re forced to boot from another system and attempt the change via chroot. Even then, it’s messy. For those who want a system without systemd, Devuan now has a legitimate place, even for technically inclined users.

Why might one avoid systemd:

1. Simplicity and predictability: Traditional init systems are easy to debug, less opaque, and don’t pull in a large web of dependencies.

2. Resource footprint: Sysvinit or OpenRC can run with minimal memory and CPU usage, ideal for very small servers or embedded systems.

3. Control: Fewer hidden processes and services mean you can strip down and tune exactly what runs at boot.

Reasons to stick with systemd:

1. Ubiquity: Most packages, especially in Trixie, assume systemd is present. Running without it often leads to breakage or fragile setups.

2. Service management features: systemd provides dependency-based service startup, logging, timers, and cgroup integration out of the box.

3. Easier integration with modern software: Many newer server tools and desktop components expect systemd and may not work properly without it.

Systemd Makes Sense for Most Users

For the majority of us, systemd offers clear advantages and a cohesive, performant set of system daemons that do their job reliably. It’s unfortunate, however, that the long tradition of Debian giving users choice in init has essentially come to an end.

For those disappointed by this, Alpine is worth a look. Alpine is a super minimal distribution based on BusyBox. It uses the musl C library and remains impressively small while still offering a well-curated and thorough selection of packages. And of course, Devuan. Devuan is a Debian fork whose claim to fame is being systemd-free. Any packages that would normally depend on systemd have been adjusted or patched for a smooth experience, including things like elogind replacements and tweaks to GNOME dependencies.

Final Thoughts

Debian used to be a super-flexible system that could be stripped down and tuned to run in very small memory footprints. It mostly still is, but with Trixie, it’s just a bit less flexible, and that’s truly too bad. They broke a decades-long tradition.

For those who are really bothered by this, thankfully there is Alpine and Devuan.

Whether you preferred sysvinit, OpenRC, or runit, Debian gave you the tools to do it.

With Debian 13 Trixie, that is basically over.
