>
> 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.
