Abstract: Systems and methods are provided for implementing booting from an operating system (“OS”) subset. In various embodiments, an OS management system deploys an OS image to a device, the OS image corresponding to a fully functional OS that is configured to manage hardware and software resources of a computing system on which the fully functional OS is installed. The fully functional OS is partitioned into a plurality of OS subsets corresponding to a plurality of functionalities that the fully functional OS is capable of implementing when the plurality of OS subsets has been initialized. The OS management system receives a user selection indicating selection of a first set of OS subsets among the plurality of OS subsets, and initializes the first set of OS subsets without initializing other OS subsets among the plurality of OS subsets, based on the user selection.

Abstract: A method and system for unified diagnosis of a network incident is provided. The unified diagnostics system is comprised of a monitoring tool, a network layer including a firewall, and a policy engine. The monitoring tool is invoked by a user in order to diagnose a network incident. The network layer and the policy engine generate various events that provide a history of their processing, and the monitoring tool collects these events. When the user attempts a network activity that fails, the network layer places an event notification in a notification queue. Then the monitoring tool analyzes the event notifications to identify events that are related to the same network incident. After analyzing the network incident and event information, the user can take the necessary action to correct the problem that caused the incident.
