Systemd vs SysVinit vs OpenRC in Scripts

Abstracting service restarts across different distributions:

restart_service() {
    local svc="$1"
    if command -v systemctl >/dev/null 2>&1; then
        systemctl restart "$svc"
    elif command -v rc-service >/dev/null 2>&1; then
        rc-service "$svc" restart
    elif [ -x "/etc/init.d/$svc" ]; then
        "/etc/init.d/$svc" restart
    else
        echo "No supported init system found" >&2
        return 1
    fi
}
