What are the Supported Options in fuse-overlayfs?

Does `fuse-overlayfs` support all options of `mount -t overlayfs` ?
It seems to recognize `volatile` but not recognize `metacopy=on` .

`unknown argument ignored: metacopy=on`

here is the command used :

`fuse-overlayfs -o lowerdir="${v_lowerdir}",upperdir="${v_upperdir}",workdir="${v_workdir}",volatile,metacopy=on "${v_merged}"`
