Its really important to understand that puppet and the like cannot (without heavy engineering) act as a task dispatcher. The big feature of "DCOS" is task distribution. In linux terms its like comparing the CPU scheduler to chmod. Yes you can make a program run by chmoding a file to +x, but its the scheduler that is responsible for making sure the programme has CPU time.

Task distribution primitives are handled by Mesos and implemented in the various apps running on Mesos (Marathon, Chronos, etc.) It seems inaccurate to call this a feature of DCOS. Puppet and the like can easily configure and manage Mesos and the various apps running on top, giving all the task dispatch functionality goodness. DCOS will hopefully be a great integrated Mesos distribution. Seems to me that by supporting machine provisioning and having a per-node licensing model, it's being positioning as a direct competitor to Openstack and VMWare.
