But then you have to be careful not to remove the one which happens to be the "original" or the hardlinks will break, right?

  No, pointing to an original is how soft links work. Hard links are all equivalent. A file has any number of hard links, and at least in theory you can't distinguish between them. The risk with hardlinks is that you might alter the file. Reflinks remove that risk, and also perform very well.

    Thank you, I was unaware of this. However, the fact that editing one copy edits all of them still makes this a non-solution for me at least. I'd also strongly prefer deduping at the block level vs file level.

      I would suspect a call to $(chmod a-w) would fix that, or at least serve as a very fine reminder that there's something special about them
