> Current LCE (DockerLinuxContainerRuntime) is mounting /etc/passwd to the container. And it seems uses wrong file name "/etc/password" for container.
> {panel}
> .addMountLocation("/etc/passwd", "/etc/password:ro");
> {panel}
> The biggest issue of bind-mount /etc/passwd is that it overrides the users defined in Docker image which is not expected. Remove it won't affect existing use cases.
