Comment 2 is designed to solve a different problem and won't catch the
tarball on disk getting corrupted because it will simply be comparing
a cached checksum in the .done file with the stated checksum in the
recipe.

I'm not sure what points in the Builld Performance page mean you
couldn't trust the resulting image.  There are some tweaks that mean
data loss in the event of power failure (ie no journal, high write
delay) but in this situation the corrupted disk can be reformatted as
it only contains built objects and can be entirely regenerated.
