why the FUCK did i think making an init selector was a good idea
artix themselves dont even ship services in their online installer
they just give you a bare system and say "figure it out" and
it WORKS because people can just install their init of choice
afterwards. but nooooo i had to be clever and build a whole
netinstall-add monstrosity with openrc/runit/s6 service groups
that broke constantly because basestrap --overwrite is a lie
and init packages conflict with each other and sddm-openrc +
lightdm-openrc both Provide: init-displaymanager and pacman
just goes 🖕 during install.
so anyway. dinit only now. you want something else? read
changing-init.md, i literally copied the artix wiki tutorial.
i am not maintaining four init service groups in netinstall.yaml
for the rest of my life. this is my villain origin story.
actual changes:
- ripped out offline calamares mode (was never truly offline)
- ripped out packagechooser.conf (good fucking riddance)
- added packagechooser_dm.conf so you can at least pick your DM
- added BYODE offline installer (bare system + btrfs + snapper,
no DE, you pacman -Sy plasma-meta yourself)
- added yay + snapper + btrfs-progs to rootfs
- shoved Init Services + DM groups into netinstall.yaml (dinit
only, obviously)
- updated every markdown file that mentioned another init like
they were cursed (they were)
- wrote changing-init.md so i can just paste the link next time
someone asks
- X-KDE-IsAdminApplication=true so KDE stops acting like
calamares is a virus (its not, its just desperate)

# Changing init on an installed system
|
|
|
|
Antergos NeXT ships with **Dinit** as the default and only install-time init.
|
|
If you prefer a different init (OpenRC, Runit, or S6), you can switch after
|
|
installation.
|
|
|
|
> **Warning:** Switching init is for advanced users. In general, a fresh
|
|
> installation is safer. Keep a bootable Artix LiveUSB handy in case
|
|
> something goes wrong.
|
|
|
|
## Overview
|
|
|
|
1. Stop your display manager and get to a TTY
|
|
2. Save a list of installed `-dinit` service packages
|
|
3. Download the corresponding `-<newinit>` packages
|
|
4. Remove the dinit packages
|
|
5. Install the new init packages
|
|
6. Enable services for the new init
|
|
7. Cold reboot
|
|
|
|
## Step-by-step
|
|
|
|
### 1. Stop the display manager
|
|
|
|
```bash
|
|
dinitctl stop sddm # or lightdm / lxdm / greetd / ly
|
|
```
|
|
|
|
Switch to a text TTY with Ctrl+Alt+F2 and log in as root.
|
|
|
|
### 2. Save your service list
|
|
|
|
```bash
|
|
pacman -Qsq dinit > services.list
|
|
```
|
|
|
|
This captures every installed package with `-dinit` in its name.
|
|
The list will include things like `sddm-dinit`, `networkmanager-dinit`,
|
|
`elogind-dinit`, etc.
|
|
|
|
### 3. Download packages for the new init
|
|
|
|
Replace `openrc` with `runit`, `s6`, or your init of choice:
|
|
|
|
```bash
|
|
pacman -Sw $(sed 's/dinit/openrc/g' < services.list)
|
|
```
|
|
|
|
This fetches the packages into pacman's cache without installing them.
|
|
If this fails for any package, you'll need to install it manually later.
|
|
|
|
### 4. Remove the old init packages
|
|
|
|
```bash
|
|
pacman -Rdd $(cat services.list)
|
|
```
|
|
|
|
The `-dd` flag bypasses dependency checks — required because we're
|
|
ripping out the entire init layer at once.
|
|
|
|
### 5. Install the new init
|
|
|
|
First install the base init package and elogind:
|
|
|
|
| Target | Base packages |
|
|
|----------|---------------|
|
|
| OpenRC | `openrc`, `elogind-openrc` |
|
|
| Runit | `runit`, `elogind-runit` |
|
|
| S6 | `s6-base`, `elogind-s6` |
|
|
|
|
```bash
|
|
pacman -S openrc elogind-openrc
|
|
```
|
|
|
|
Then install the service packages:
|
|
|
|
```bash
|
|
pacman -S $(sed 's/dinit/openrc/g' < services.list)
|
|
```
|
|
|
|
### 6. Enable services
|
|
|
|
#### Switching to OpenRC
|
|
|
|
```bash
|
|
rc-update add sddm default
|
|
rc-update add NetworkManager default
|
|
# ... repeat for each service
|
|
```
|
|
|
|
Common services: `acpid`, `bluetoothd`, `cronie`, `cupsd`, `dbus`,
|
|
`dhcpcd`, `NetworkManager`, `power-profiles-daemon`, `syslog-ng`.
|
|
|
|
#### Switching to Runit
|
|
|
|
```bash
|
|
ln -s /etc/runit/sv/NetworkManager /etc/runit/runsvdir/default/
|
|
ln -s /etc/runit/sv/sddm /etc/runit/runsvdir/default/
|
|
# ... repeat for each service
|
|
```
|
|
|
|
#### Switching to S6
|
|
|
|
```bash
|
|
s6-service add default NetworkManager
|
|
s6-service add default sddm
|
|
# ... repeat for each service
|
|
```
|
|
|
|
### 7. Cold reboot
|
|
|
|
A normal reboot won't work because the symlinks for `/sbin/init` and
|
|
`/sbin/reboot` still point to the old init. Instead, synchronize
|
|
disks and trigger a cold reboot:
|
|
|
|
```bash
|
|
sync
|
|
mount / -o remount,ro
|
|
echo b > /proc/sysrq-trigger
|
|
```
|
|
|
|
Or use the reset button on your machine.
|
|
|
|
## Troubleshooting
|
|
|
|
### System won't boot
|
|
|
|
Boot from an Artix LiveUSB, chroot in, and check:
|
|
|
|
```bash
|
|
mount /dev/sdXn /mnt
|
|
artix-chroot /mnt
|
|
```
|
|
|
|
From the chroot, you can reinstall packages, fix service symlinks,
|
|
or regenerate the initramfs with `mkinitcpio -p linux`.
|
|
|
|
### Missing service packages
|
|
|
|
Some daemons may not have init scripts for your chosen init.
|
|
Check the Artix repos:
|
|
|
|
```bash
|
|
pacman -Ss <daemon-name>-openrc # or -runit, -s6
|
|
```
|
|
|
|
If a package doesn't exist, you can write a custom service file
|
|
or use a different daemon.
|
|
|
|
### OpenRC: services don't enable on installed systems
|
|
|
|
This was a known bug in earlier Antergos NeXT builds (the installer
|
|
used `artix-service` which didn't set up OpenRC correctly).
|
|
If you're switching to OpenRC manually on an already-installed system,
|
|
`rc-update add` works fine — the bug was specific to the installer flow.
