so largefile will get deduped in the example below.
And you can use 'zdb -S' (which is a lot better now than it used to
be before dedup) to see how much benefit is there (without even
turning dedup on):
forgive my ignorance, but what's the advantage of this new dedup over
the existing compression option? Wouldn't full-filesystem compression
naturally de-dupe?
