I don't think we're using container system similarly. I'm using the term "Container" in the way Docker describes:
>A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.[0]
If you cannot package system tooling, system libraries, and configuration with your software I don't think what you're building is a container system. If you also loose the sorcery benefits docker's network namespaces and volume drivers you're loosing a lot of functionality that docker provides.
I wouldn't call the JVM, RVM, V8/SpiderMonkey, cPython, and any other language VM a "container system" even though many of them allow you to set up platform isolation, restriction, and sandboxing.
I use "container" to reference a technology that allows me to build, package, ship, and orchestrate the execution of these units.
