> This is because there's no ordering between the execution of the 'isolate()' method of the CNI isolator and the execution of the preparation scripts in ContainerLaunchInfo.
> For command tasks, currently, we do a recursive bind mount (<rootfs> -> <sandbox>/.rootfs) in the preparation script returned by the linux filesystem isolator (same as other volumes). The command executor will then pivot_root into <sandbox>/.rootfs.
> As a result, depending on the timing. the /etc/xxx files mounted at <rootfs>/etc/xxx might or might not be present in the rootfs for command tasks.
