Dinit

Dinit is a modern init system designed for speed and correctness. Written in C++, it focuses on parallel service startup and dependency management. Dinit is the default init system in Antergos NeXT.

Dinit handles dependencies automatically through declarative configuration files, avoiding the complexity of shell-script-based service definitions.

Key concepts

Concept What it means
Service files Declarative .conf files in /etc/dinit.d/
Dependencies Automatic — Dinit figures out start order from depends-on directives
Parallel startup Very fast — starts services concurrently wherever possible
Process supervision Optional — can restart crashed services if type = process

Basic commands

# Start a service
dinitctl start sshd

# Stop a service
dinitctl stop sshd

# Enable at boot
dinitctl enable sshd

# Disable at boot
dinitctl disable sshd

# Check status
dinitctl status sshd

# List all services
dinitctl list

Example service file

/etc/dinit.d/sshd.conf:

type = process
command = /usr/bin/sshd -D
depends-on = dbus
depends-on = network

Where services live

  • System services: /etc/dinit.d/ (config) — enabled via symlinks in /etc/dinit.d/boot.d/
  • User services: similar structure under the user’s config directory (for dinit-user-spawn)
  • Boot-enabling: dinitctl enable <service> creates a symlink in boot.d/

Service files use a simple key-value syntax. The type can be:

  • process — supervised (auto-restart on crash)
  • scripted — runs and completes (one-shot tasks)
  • internal — handled internally by dinit

Common tasks

Enable a service at boot

dinitctl enable sshd

Alternatively, create a symlink manually:

ln -s /etc/dinit.d/sshd /etc/dinit.d/boot.d/

Check what’s running

dinitctl list

View logs

Dinit itself doesn’t handle logging. Services log to syslog or their own log files under /var/log/. Use less /var/log/messages or check per-service log directories.

Comparison with OpenRC

  OpenRC Dinit
Service format Shell scripts Declarative config
Dependencies Manual (need/use) Automatic
Speed Fast Very fast (more parallel)
Complexity Low Medium
Supervision No built-in Optional

Troubleshooting

Service fails to start

Check the service file syntax first:

dinitctl start sshd
# If it fails, check:
cat /var/log/messages | grep dinit

Make sure all depends-on services are available (even if not enabled — dinit will start them as dependencies).

“boot” service file missing

Dinit’s add_user_svc_dinit in Calamares attempts to create boot.d/ symlinks but does not create a boot service file. This is a known upstream limitation. Workaround: ensure services are enabled via dinitctl enable after install, or use the init-specific package handling in Calamares.

pipewire doesn’t start

On Antergos NeXT, artix-pipewire-launcher is patched to support dinit. If pipewire isn’t starting, verify the launcher script at /usr/bin/artix-pipewire-launcher includes dinit in its supported init list. The XDG autostart entry at /etc/xdg/autostart/pipewire.desktop handles starting pipewire on login.

When to use Dinit

Dinit is suitable for users who want fast boot times and automatic dependency resolution without managing shell-script-based service files. It is the default init in Antergos NeXT and requires no additional configuration.

Users migrating from systemd will find Dinit’s declarative service files familiar. Users accustomed to OpenRC or Runit may prefer to switch — see Changing init for instructions.
