Artix Linux: Choosing an Init System Before Installation

You want Arch packages without systemd. Which init system should you commit to?

Artix Linux is an Arch Linux-based distribution that replaces systemd with a choice of init systems: runit, s6, OpenRC, and dinit. An init system is the first process the kernel starts; it launches and supervises background services. Because Artix maintains its own package repositories and signing keys separate from Arch, the init choice is not just a cosmetic preference. It determines which service scripts are available, how you enable services, and how easily you can install software from the Arch User Repository (AUR).

Switching init systems after installation is possible, but it can leave residual service files and require manual cleanup. The practical takeaway is to decide during installation or before you heavily customize services, then verify the Artix keyring and repository configuration.

What changes when systemd is removed

Artix retains access to most Arch packages and the AUR, but service management moves from systemctl and systemd unit files to the init system you select. Artix repositories provide init scripts and service definitions for that init system. Arch mirrors remain available for ordinary packages. The two ecosystems use different package signing keys, so the artix-keyring package must be installed and trusted for updates to succeed.

Exact repository URLs, package names, and service directory locations can change between Artix releases. The checks below are diagnostic starting points, not a guarantee that paths match your installed version.

Verify the active init system and repository trust

Run these read-only commands on the Artix host as a regular user. They do not change system state.

command -v runit
command -v openrc
command -v s6-rc
command -v dinit

Each command prints a path such as /usr/bin/openrc if that init system is installed. If none print a path, the system may still be using systemd or the binaries may not be in your current PATH.

pacman -Q artix-keyring

Expected output confirms the Artix keyring package is installed. If the command reports that the package is not found, package signature verification may fail during updates.

grep -n "artix" /etc/pacman.conf

Expected output shows Artix repository entries. If nothing matches, Artix repositories may not be configured, or the file may use different section names in a newer release.

Risk: these commands only confirm presence, not trust or validity. Key trust and repository health still need to be confirmed through Artix documentation and successful package updates.

runit, OpenRC, s6, and dinit: a decision frame

Init system	Service model	Typical fit
runit	Directory-based supervision; each service is managed through its own service directory	Minimal systems where simple service start and stop is enough
OpenRC	Init scripts with dependency declarations and runlevel-like grouping	Administrators who want explicit service ordering
s6	Supervision primitives and service databases	Users comfortable with supervision toolchains
dinit	Dependency-based service manager with service definition files	Systems needing dependency resolution without systemd

This table describes general init-system behavior; Artix-specific packaging and service definitions should be confirmed against current Artix documentation. This document does not compare boot speed because actual startup time depends on enabled services and hardware.

Worked example: checking an AUR package for systemd assumptions

Some AUR packages install .service unit files that systemd would process, but Artix does not run systemd by default. Before installing AUR software, inspect the PKGBUILD file for systemd references. This is a read-only review step.

grep -n "systemd" PKGBUILD

Run this inside the extracted AUR package directory as a regular user. If the output lists install commands, unit files, or systemctl calls, the package may not work as intended on Artix unless you adapt it manually. Absence of output does not guarantee compatibility; it only means the build file does not mention systemd by name.

Risk: modifying PKGBUILDs or manually creating service definitions requires understanding the target init system. This is an advanced step and is not covered here.

Limitations

• Artix package names, repository URLs, and service paths may change between releases. Verify against current Artix documentation before automating updates or scripting service management.
• Switching init systems after installation can leave residual service files. No specific cleanup steps are provided here because residual locations depend on the init systems involved.
• Not all AUR packages assume a non-systemd init. Treat any package that installs systemd units as potentially unsupported on Artix.

Bottom line

Choose your init system at Artix installation time. Verify artix-keyring and Artix repository entries in /etc/pacman.conf after install. Inspect AUR PKGBUILDs for systemd references before installing user-submitted software. If you later need a different init system, plan for manual cleanup rather than assuming a clean switch.
