> In the current implementation, when privileged=true, --user flag is also 
> passed to docker for launching container.  In reality, the container has no 
> way to use root privileges unless there is sticky bit or sudoers in the image 
> for the specified user to gain privileges again.  To avoid duplication of 
> dropping and reacquire root privileges, we can reduce the duplication of 
> specifying both flag.  When privileged mode is enabled, --user flag should be 
> omitted.  When non-privileged mode is enabled, --user flag is supplied.
