dedup works at the file level. Here we're talking about files that are
highly similar but not identical. I don't want to rewrite an entire file
that's 99% identical to the new file form, I just want to write a small
set of changes. I'd use ZFS to keep track of which blocks change over time.
I've been asking around, and it seems this capability doesn't exist
*anywhere*.
