Out of band layer scrubbing

Abstract:

Application layering is a technology that separates applications from an operating system image. In some cases, information inside an application layer needs to be modified when that layer is delivered to a computer to be executed correctly in a specific environment. Described is a technique to allow those operations to be defined and executed outside of the operating system that will be running the application layer, so that a single application layer can be delivered to heterogeneous end points without the need to take up additional computation on the guest machine it is being delivered to, to ensure application compatibility when applications reside in more than one layer, to install applications into a layer without knowledge of a specific platform, and to modify the image to provide the required drivers and services to support any platform.
