I totally agree about both statements. My next hands on and post on that topic will be about moving from Ubuntu to CoreOS and what it implies for our existing infrastructure (I'm the article author)
We need a cross-distro dependency manager that can generate app-liance images for baremetal, lxc, kvm, aws/xen, vmware, azure/hyperv, illumos/bsd/zones, etc. Such a dependency manager could encode management-related policy (e.g. networking) into an image manifest that could be parsed by deployment tools. As an image format, OVF was ratified by DMTF and may have useful concepts, http://en.wikipedia.org/wiki/Open_Virtualization_Format
