Abstract: A master daemon (a dedicated program component) is provided for a computer operating system which utilizes selected criteria to perform actions in one or more domains, as defined. The master daemon provides application program interfaces (APIs or facilities) and monitors all requests (for which the master daemon is configured) directed to the associated computing base including the operating system. All requests are in the form of encapsulated information as defined. In general, the master daemon, in response to such requests, performs the actions, each constrained to operate exclusively in a single domain. Selected criteria that may be contained in encapsulated information may define a higher-order multidimensional domain space for segregating system operational functionality according to configured boundaries.
