[PATCH openbmc 00/16] Update flash update to be useable at runtime for v1.0-stable

The underlying storage for a file system can not be updated when it is in use.  The initial solution was to update the flash as the system was being shutdown, with output to the console.

Updates were made to the `init` script that allows the flash to not be used for a given boot but the `update` script was not updated for error handling, and no documentation was provided to prepare the system for this mode.

When combined with openbmc/skeleton#111 this series is intended to address #293 by providing for the flash to be written while running the full stack after a `PrepareForFlash` mode has been initiated.

This also has fixes for saving files fixing #378.

These are the changes in #297 applied to the v1.0-stable branch.
