That's a question for the GNU coreutils people, since that's how they implemented it. I thought that the copy_file_range system call would try to do a clone first, but it looks like that behavior changed a while ago. Now the system call will only attempt a clone on filesystems that don't specifically implement copy. Anna > > Ced
