启用 Ubuntu Pro 后，我注意到我的服务随机出现故障。
经过调查，原来 Docker rootless 服务正在被 Livepatch 关闭。看起来 Livepatch 将停止整个非 root 用户会话，只是检查补丁。
为什么会发生这种情况？我可以限制 Livepatch 仅在有补丁时停止服务吗？或者在特定时间运行？
我按照论坛中的快速设置指南进行操作： https://discourse.ubuntu.com/t/ubuntu-pro-beta-tutorial/31018 并使用官方 repos 设置无根 docker。
我认为在使用以 root 身份运行的 docker 进行测试时没有遇到同样的问题。
