Little things that matter in language design
The two files can be changed independently without affecting each other. One could be deleted, truncated, expanded, chmoded, have new acls set, etc.
The actual block sharing is just an implementation detail...it could be implemented as a lazy copy for example.
a reflink would be a new type of inode

Surely there's a better name for a make-a-copy-of-this-inode-and-all-its-data-and-maybe-do-some-cool-COW-magic system call. It's too bad that the "dup" family of system call names is already used for something with a completely separate meaning.
