# systemd deployment

This directory contains the versioned systemd deployment used for the Debian runtime.

## Install

Run the installer as `root` and point it at the live runtime root:

```bash
cd /path/to/m2dev-server
python3 deploy/systemd/install_systemd.py \
  --user mt2.jakubkadlec.dev \
  --group mt2.jakubkadlec.dev \
  --runtime-root /home/mt2.jakubkadlec.dev/metin/runtime/server \
  --channel 1 \
  --channel 99 \
  --restart
```

`--channel-limit 1` is also supported and will auto-include channel `99` when present in `channels.py`.

## What it installs

- `metin-server.service`
- `metin-db.service`
- `metin-db-ready.service`
- `metin-auth.service`
- `metin-game@.service`
- `/usr/local/libexec/metin-game-instance-start`
- `/usr/local/libexec/metin-wait-port`

The `metin-db-ready.service` gate waits until the DB socket is actually accepting connections before `auth` and `game` units start.
