4.0.0 Beta 在 iStoreOS 24.10.5 下 Docker 启动失败

在 Debian 12 x86_64下运行是正常的，相同的设备在 iStoreOS 下运行错误日志

可以确定 iStoreOS 的 Linux 内核不支持 devtmpfs

root@iStoreOS:~# mount -t devtmpfs none /dev2
mount: /dev2: unknown filesystem type 'devtmpfs'.
       dmesg(1) may have more information after failed mount system call.

需要开启内核编译选项

CONFIG_KERNEL_DEVTMPFS=y

别关闭啊。devtmpfs本来就不是必须的，为啥不直接bind /dev到/xunlei/dev呢？

@cnk3x

xunlei/pkg/vms/options.go

Line 36 in 2aa3bab

sys.MountOptions{Target: filepath.Join(ro.root, "dev"), Source: "devtmpfs", Fstype: "devtmpfs", Data: "mode=0755"}, //tmpfs

这里为什么不直接将/dev绑定到/xunlei/dev？也就是mount --bind /dev /xunlei/dev。
不管是宿主还是容器内，/dev肯定都已经由系统管理，该有的文件都有了。

而且我估计迅雷只需要这些基本的dev就行了：

fd
full
null
zero
urandom
random
console
stderr
stdin
stdout

mount --bind /dev /xunlei/dev就兼容使用tmpfs的系统了
