x86-64 lean‘s openwrt昨天重新编译，无法启动docker，提示
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
Dockerman只显示概览页，系统日志截取如下：

内核日志有关的两行如下：
[34.549195] overlayfs: filesystem on '/mnt/sda3/Docker/check-overlayfs-support563574997/upper' not supported as upperdir
[34.554882] overlayfs: filesystem on '/mnt/sda3/Docker/check-overlayfs-support403829808/upper' not supported as upperdir
在概览页重新开关Docker Daemon后，系统日志是差不多的，估计是一样的问题：

请教老大，我这是openwrt编译时缺了某个组件，还是哪里设置出了问题？求助如何设置。
Devices cgroup isn't mounted
请用https://raw.githubusercontent.com/coreos/docker/master/contrib/check-config.sh 检查内核模块是否完备
check-config.sh在openwrt下无法运行呢
env: can't execute 'bash': No such file or directory
貌似openwrt下的busybox支持ash、hush、msh三种shell,但是不支持bash

这个自行解决吧
我注意到日志里有这条failed to connect to {unix:///var/run/docker/containerd/containerd.sock
实质应该连接的sock是unix:///var/run/docker.sock
containerd.sock和docker.sock的区别，但是不知道在哪里出错了，自动连接了containerd.sock。设置里面明明是unix:///var/run/docker.sock这个

containerd 是比 docker 更底层的，不和 dockerman 直接沟通，你是由于无法链接 containerd，导致 docker daemon 起不来
