With the ZFS on FreeBSD moving to ZoL, does anyone know what's the 
current status of supporting UnionFS on ZFS? Last time I checked FreeBSD 
implementation lacked the "whiteout" feature required to properly 
support deleting files in upper layers. Does OpenZFS or ZoL provide any 
updates to properly supporting UnionFS on ZFS?
