修改直接 docker进入相关容器 修改 /root/.lightning/config，重启服务后就会丢失。
经过和 GTP 沟通，最终的解决方案如下：
关于在Docker环境中使用docker-compose.yml配置文件持久化c-lightning的experimental-dual-fund配置。您提到在重启容器后之前的修改会丢失。
我们最终的解决方案是直接在docker-compose.yml文件中的c-lightning服务定义里通过LIGHTNINGD_OPT环境变量添加experimental-dual-fund=true，确保这项配置在c-lightning启动时被正确应用并持久化。之后，您需要运行以下命令来重启Docker服务。
