# Enshrouded dedicated server with Kiln: one unit per kilnctl instance (~/.config/kiln/instances/%i.toml).
# User unit. Install (docs/kiln/kilnctl.md):
#   install -Dm644 runner/systemd/kiln@.service ~/.config/systemd/user/kiln@.service
#   systemctl --user daemon-reload && systemctl --user enable --now kiln@<name>
#   loginctl enable-linger "$USER"     # only to run without a login session (boot start)
# Expects kilnctl in ~/.local/bin (cargo install --path runner/kilnctl --root ~/.local); adjust the paths otherwise.

# A crash loop gives up after 5 failed starts in 10 minutes.
StartLimitIntervalSec=10min

[Service]
Type=exec
# Ntsync, port, prefix, exe, enshrouded_server.json, Kiln files; a failure keeps the server from starting.
ExecStartPre=%h/.local/bin/kilnctl preflight %i
# Foreground: SIGINT/SIGTERM become one SIGINT to the server, which saves and exits; then wineserver -w.
ExecStart=%h/.local/bin/kilnctl run %i
# Only kilnctl gets the stop signal (it forwards it once); whatever is left after it exits is killed.
KillSignal=SIGINT
KillMode=mixed
# The save plus Wine teardown takes ~5-15 s; this is the hard limit before SIGKILL.
