All approaches to keep OpenRC as default failed: - --ignore: pacman ignores it during fresh install provider resolution - --assume-installed=init-logind: ALPM doesn't check assume-installed for virtual providers - --ask=12: infinite loop (pacman re-adds elogind-dinit after each removal) - dummy package in custom repo: init-rc conflict hits via different path Dinit works because pacman --noconfirm naturally picks elogind-dinit (alphabetically before elogind-openrc), pulling dinit-rc which has no conflict. All inits (OpenRC, Runit, S6) remain selectable in the online installer. Changes: - buildiso: INITSYS='dinit', remove --assume-installed/--ask hacks - basestrap/main.py, packages/main.py: remove same hacks - profile.yaml: antergos-live-dinit for dinit, move openrc pkg to init-specific - packagechooser.conf (x2): default=Dinit, Dinit first in item list - packagechooser_dm.conf: *-dinit instead of *-openrc - README.md, README.pl.md, docs/*: update all OpenRC-first references - AGENTS.md: document dinit as default

# OpenRC
|
|
|
|
**OpenRC** is one of four init systems available in Antergos NeXT (the default is **Dinit**). It's used by Gentoo, Artix Linux, Devuan, Alpine Linux, and other non-systemd distros. It's proven, well-maintained, and about as simple as an init system can get while still being feature-rich.

## systemd vs OpenRC at a glance
|
|
|
|
| | systemd | OpenRC |
|
|
|---|---|---|
|
|
| Philosophy | "One tool to rule them all" | "Do one thing well (Unix way)" |
|
|
| Logs | `journalctl` (binary logs) | Plain text files in `/var/log/` |
|
|
| Service mgmt | `systemctl start/stop/enable` | `rc-service start/stop`, `rc-update add/del` |
|
|
| Dependency | Parallel + automatic | Manual or explicit `need/use/before/after` |
|
|
| Config files | `.service` units (INI-like) | Shell scripts in `/etc/init.d/` |
|
|
| Size | ~80+ binaries, 500k+ lines | ~15 binaries, ~30k lines |
|
|
| Scope | PID 1 + logind + resolved + timedated + networkd + ... | Just PID 1 |
|

OpenRC is used by Gentoo, Artix Linux, Devuan, Alpine Linux, and other non-systemd distros. It's not as mainstream as systemd, but it's proven and well-maintained.

### Service management
|
|
|
|
| Task | systemd | OpenRC |
|
|
|------|---------|--------|
|
|
| Start a service | `sudo systemctl start sshd` | `sudo rc-service sshd start` |
|
|
| Stop a service | `sudo systemctl stop sshd` | `sudo rc-service sshd stop` |
|
|
| Enable at boot | `sudo systemctl enable sshd` | `sudo rc-update add sshd` |
|
|
| Disable at boot | `sudo systemctl disable sshd` | `sudo rc-update del sshd` |
|
|
| Check status | `systemctl status sshd` | `rc-service sshd status` |
|
|
| List enabled | `systemctl list-unit-files --enabled` | `rc-update show` |
|
|
| View logs | `journalctl -u sshd` | `less /var/log/messages` |
|
|
|
|
### Key commands
|
|
|
|
```bash
|
|
# List all services with their runlevel
|
|
rc-status
|
|
|
|
# List enabled services
|
|
rc-update show
|
|
|
|
# Add a service to a runlevel
|
|
rc-update add <service> <runlevel>
|
|
|
|
# Remove a service
|
|
rc-update del <service> <runlevel>
|
|
|
|
# Start/stop/restart a service
|
|
rc-service <service> start
|
|
rc-service <service> stop
|
|
rc-service <service> restart
|
|
```
|
|
|
|
Runlevels in OpenRC work like directories under `/etc/runlevels/`:
|
|
|
|
```
|
|
/etc/runlevels/
|
|
├── boot # Low-level system services (filesystems, udev, etc.)
|
|
├── sysinit # System initialization (hwclock, hostname, etc.)
|
|
├── default # Normal boot services (NetworkManager, sshd, etc.)
|
|
└── shutdown # Shutdown services
|
|
```
|
|
|
|
## Why did Antergos NeXT switch?
|
|
|
|
Three reasons:
|
|
|
|
1. **systemd grew beyond an init system** — it now owns logind, resolved, timedated, networkd, homed, and more. It's no longer just PID 1. It's a full OS management suite with a scope that keeps expanding.
|
|
|
|
2. **systemd dropped SysV compatibility** — version 260 (March 2026) removed `systemd-sysv-generator`, `rc-local.service`, and all legacy compatibility code. If your distro isn't 100% systemd-native, it breaks.
|
|
|
|
3. **systemd's age verification PR** — [#40954](https://github.com/systemd/systemd/pull/40954) (merged Mar 2026) added `birthDate` fields to userdb JSON for age verification compliance. Optional today, precedent tomorrow. We don't want our OS to ask for your age.
|
|
|
|
OpenRC doesn't do any of that. It starts services and gets out of the way.
|
|
|
|
## Will things break?
|
|
|
|
Probably not. Most desktop software doesn't care about the init system. Browsers, editors, games, media players — they all work the same.
|
|
|
|
Things that **do** care about systemd and won't work:
|
|
- `systemctl`, `journalctl`, `loginctl`, `timedatectl` — obviously
|
|
- GNOME (it dropped non-systemd support)
|
|
- Any `.service` file you try to run directly (they're systemd-native)
|
|
|
|
But everything you actually use day-to-day? Works fine. And if you need to check logs, they're in `/var/log/messages` — plain text, no `journalctl` required.
