A system and method for generating run-time images of a software program, such as an operating system, builds a run-time image from a plurality of selected software program components, each of which is a discrete packet of functionality. Each component not only specifies its properties and resources but also provides script for its own build behavior. To build the run-time image, a configuration is constructed to include instances of selected components, and the scripts of the instances are invoked such that each component instance builds itself into the run-time image. A general framework is provided for managing the components and the build process. A prototyping scheme is provided for a component to inherit its properties, resources, and script from other components. Each component may also specify dependency data in terms of component inclusion in the run-time image and the orders in which the components are built into the run-time image. A versioning scheme facilitates the tracking of various revisions and upgrades of components.
