I’m afraid I’m behind on the c/storage PR, but, how does this work?
AFAICS this means that chunkedDiffer.tarSplit is closed by the time this function returns.
But, just below, PrepareStagedLayer ultimately calls chunkedDiffer.ApplyDiff, which copies differ.tarSplit to out.TarSplit. This function stores out to diffOutputs and returns, closing tarSplit.
Later, createNewLayer calls ApplyStagedLayer, and that, in applyDiffFromStagingDirectory, tries to read an already-closed file.
What am I missing?

Note to self: this will be correct with containers/storage#2323 .

The part that ensured differ.Close was called (and that motivated breaking the API to s/Get/New/ here) got lost?!

sorry I missed the error path on s.imageRef.transport.store.PrepareStagedLayer(), because later on CleanupStagedLayer takes care of it.
Do you prefer to have the differ.Close() just there or through a new defer function?

containers/storage#2323 now documents on NewDiffer that
The caller must call Close() on the returned Differ.
so I’d prefer doing exactly that — defer seems easiest.
