Rsync and improved efficiency for CoW filesystems

[Remi Gauvin via rsync]

I was trying to figure out if there was a way for sync to use reflinks
to more efficiently use disk space on CoW filesystems.

I found this thread in the bugtracker, but was wondering if there was
any more recent progress on the idea?
