Description

We are attempting to run mesos-slave 0.23 in a container. However it appears that the mesos-slave agent registers as a new slave instead of re-registering. This causes the formerly-launched tasks to continue running.

systemd unit being used:

ps, yes I saw the coreos-setup repo was deprecated.
