   I'll be adding support for it when the next libuv update is merged. My guess is that it will be backported to Node 8, as most of the work happens in libuv.

   Relevant paragraph from libuv docs:

   .. c:function:: int uv_fs_copyfile(uv_loop_t* loop, uv_fs_t* req, const char* path, const char* new_path, int flags, uv_fs_cb cb)
   Copies a file from path to new_path. Supported flags are described below.
   —————————————————————————————
   - UV_FS_COPYFILE_FICLONE: If present, uv_fs_copyfile() will attempt to
   create a copy-on-write reflink. If the underlying platform does not
   support copy-on-write, then a fallback copy mechanism is used.
   —————————————————————————————
   .. versionchanged:: 1.20.0 UV_FS_COPYFILE_FICLONE is supported.
