regression-update for 1575572.
After 1575572 was checked in we observed.
We have been able to repro the issue and can observe that dpkg seems to start docker on “16.04.201605310 Daily”, but not “16.04.201605280 Daily”.
The problem seems to be that in 16.04.201605310.Daily after “dcos-docker-install.service” runs “Job for docker.service” can be seen trying to start docker. On 16.04.0-LTS, it does not try to start docker while running “dcos-docker-install.service”. Why is the binary being started now and not before?
Below are the Contents of the cloud-init, with the 3 docker installation files that fail:

regression-update for 1575572.
After the time 1575572 was checked in we observed a behavior change in the systemd init.
We have been able to repro the issue and can observe that dpkg seems to start docker on “16.04.201605310 Daily”, but not “16.04.201605280 Daily”.
The problem seems to be that in 16.04.201605310.Daily after “dcos-docker-install.service” runs “Job for docker.service” can be seen trying to start docker. On 16.04.0-LTS, it does not try to start docker while running “dcos-docker-install.service”. Why is the binary being started now and not before?
