[Service]
Type=simple
User=astrbot
Group=astrbot
# Only set what the script cannot derive from the config file.
# All XDG_*, runtime home, and UV paths are computed by setup_runtime_env()
# (called inside run_astrbot before the Python process starts).
Environment="ASTRBOT_SYSTEMD=1"
Environment="ASTRBOT_DESKTOP_CLIENT=0"
# UV_CACHE_DIR is set dynamically in setup_runtime_env (per-instance under ASTRBOT_ROOT/.cache/uv).
Environment="UV_PYTHON_INSTALL_DIR=/var/cache/astrbot/python"
# Working directory: the instance root created by `astrbotctl init`.
# The script derives all per-instance paths (ASTRBOT_HOME, XDG_*, etc.)
# from the config file at /etc/astrbot/%i.conf.
WorkingDirectory=/var/lib/astrbot/%i
# astrbotctl run reads the config, sets up the full runtime environment,
# then execs into the instance's Python/uv environment.
ExecStart=/usr/bin/astrbotctl __run_astrbot %i

# AstrBot writes to: instance data dir, and /opt/astrbot for Rust extension builds.
