           Summary: link-by-hash no-copy initialization

I have a file-server which has already received numerous backups from other
machines. I want to deduplicate existing files by the virtue of link-by-hash,
however I'd prefer not copying the data around again - instead, I want the
specified hash-directory created and used to link existing identical files into
the same inode.

Also of use would be a "relaxed" vs. "strict" mode to allow or forbid creation
of such hardlinks for files with same content and differing metadata (owner,
date, permissions, etc.)
