Abstract:

This thesis presents an approach to system initialization which is simple and easy to understand and, at the same time, is versatile in the face of configuration changes. This thesis considers initialization of a layered system. The initialization mechanism is built upon three key concepts existence of a minimal configuration, a core image of the system and dynamic reconfiguration. By assuming that the system will be running on the minimal configuration we generate a core image of the base layer of the system which, when loaded into core on any viable configuration, produces an operable base layer. As higher layers of the system are initialized dynamic reconfigurations of the lower layers are invoked to cause the system to run on the configuration actually present. The thesis also considers the problems one might encounter in implementing the many dynamic reconfigurations required by this approach to system initialization.
