Problem:
I cannot use /etc/docker/daemon.json as my start daemon for docker service. The service will fail and exit.
I also cannot use dockerd to configure service. The process will get no response.
I can only modify /usr/lib/systemd/system/docker.service to configure service successfully. is that normal?
