Docker daemon restart kills all the containers

Hello All,
I am running docker version 1.11.1 on a ubuntu 16.04. I restarted the docker daemon using “service docker restart” and all the running containers got killed.

Isn’t that a new feature of docker v 1.11.1 where containers continue run even if the docker daemon dies or restarted?

Is it something I am missing in the configuration?

Thanks,
Jeeva

Just realized that this is not 1.11.1 feature … I need to try with the experimental version
