Abstract
In a first area of a persistent memory, data is stored that defines a known good state that is operable to launch the computing device to the known good state in response to a reboot. In response to a write request to the first area of persistent memory, the requested write is directed to a second area of the persistent memory and a record of redirected writes to the second area of persistent memory is updated. A request is received to establish an update to the known good state. The updated known good state is operable to launch the computing device to the updated known good state in response to a reboot. In response to the request, the record is persisted such that in response to a reboot, the record is usable to restore the redirected writes, thereby launching the computing device to the updated known good state.
