Abstract:

Techniques for preserving state information across multiple operating environments on a machine are provided. A task engine creates and utilizes a task environment to preserve state information through multiple operating environments while sequencing the actions in a task sequence. During task sequence execution, the task environment is maintained in the machine's memory. If an action that is being executed involves initiating a reboot operation, the task environment in memory is saved to disk (i.e., non-volatile memory). When the machine completes the reboot operation, either into the same operating environment or a new operating environment, the task engine creates a new task environment in the machine's memory, and the new task environment is restored from the previously saved task environment on disk. The task engine then continues to sequence the actions in the task sequence utilizing the new task environment in memory.
