I know that a hard linked file will show the same disk usage, so if for = example: $ du a 12345 a $ ln a b $ du a b 12345 a 12345 b $ But in this case it's not the entire file being hardlinked, rather just = some parts of the file being deduplicated so it's not exactly the same. = Or is it? This is why I asked on the mailing list. :-)
