+
+if I parsed NEWS.gz correctly, that option was added in `* Noteworthy changes in release 8.0 (2009-10-06) [beta]` . So I wonder if `git-annex` could sense for version of `cp` or presence of `--reflink` option and not use it if `cp` is too old?
+
+Meanwhile I will see if there is some sensible way to get more uptodate coreutils (or `cp`) at least within conda env
