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:

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 \
  --env-file /etc/metin/metin.env \
  --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.

Optional Environment File

The runtime units support an optional EnvironmentFile for host-local overrides:

• default path: /etc/metin/metin.env
• it is loaded with EnvironmentFile=-..., so the file may be absent
• recommended ownership: root:root
• recommended mode: 0600

This is the preferred place for production-only values such as DB credentials and the admin page password.
