Oh, also, stealing code from that library doesn't resolve the questions I came here to ask; in fact it's what brought the issue to my attention in the first place. The Stratis people seem to have *blindly assumed* that *all* C-strings passed to or from the device-mapper ioctls would always be printable ASCII, and I do not trust that assumption, particularly for table parameters and target messages. zw
