Ticket #11776 (closed defect: fixed)
incomplete fs-update may leave laptop bootable

We have already fixed zhashfs to write the zero block last, which works well with laptops that have had nothing on their internal storage.
However, if the internal storage already contains an identical partition map, it is not cleared, and so a partial fs-update can leave the laptop bootable to some extent.
Proposed fix, olpc-os-builder:bin/zhashfs to write a zeroed zero block first.
