Abstract: An event subscription and publication system for dynamically notifying user level applications of kernel level events. The kernel level events may include hardware and software events as well as system level errors that occur in the kernel. User level applications that need information on these kernel level events subscribe to the event monitoring and publication framework of the present invention and are notified of these kernel level events when they occur. Upon notification of an event, the user application also is provided with specific information classifying the nature and details of the event. The kernel event monitoring and publication system of the present invention allows user level applications to be dynamically notified of kernel level events without requiring the user level application to interrupt the normal processing states to identify these events when the events occur.

Abstract: an automated method of establishing a filesystem utilizing the establishment of a first filesystem that interfaces with devices by loading software, including a first set of drivers, into memory and initializing the first set of drivers with the devices. The first filesystem is then mounted on a root directory that comprises a single storage device. The method allows input/output functionality within the first filesystem and, while input/output functionality is available to the first filesystem, the method accesses the single storage device to obtain software, including a second set of drivers. The method loads the software into the memory and initializes the second set of drivers with the devices to establish a second filesystem. The second filesystem is mounted on a root directory comprising the single storage device and another storage device and the first filesystem is then rendered inactive.
