I swear this is recent - I have never seen it before 1.8 (but maybe I am nuts). It used to be that if you used docker links, the /etc/hosts file would be updated. Now it seems that ALL containers (even those without links) have their /etc/hosts files updated to know about all containers on the local machine.

Sniffing around this look like it might be libnetwork related, but I am not 100% sure.

How do I turn this off? Container names are not what we want to be exposing to users.
