Summary:In a first area of a persistent memory, state data is stored that defines a known good state that is operable to launch a computing device to the known good state in response to a reboot. Allocation information indicative of free and allocated portions of the persistent memory is accessed. In response to a write request to the first area of persistent memory, when the write request is to an allocated portion of the persistent memory, the requested write is redirected to a second area of the persistent memory. A record of redirected writes to the second area of persistent memory is updated. When the write request is to a free portion of the persistent memory, the write request is allowed to be executed in the first area of persistent memory. The record of redirected writes is updated with the writes to the second area of persistent memory.
