 Well, my _setup_ doesn't fail, but when the cryptsetup hook runs, it
 will in my setup invoke dmsetup in a way that will fail (i.e. it will
 call dmsetup to request information on a device which is unknown to
 dmsetup).  So what you did was to silence the error, but what I
 proposed in #388871 is to not cause the error in the first place by
 checking whether the device is known to dmsetup or not at the same
 time.

 In short, the current and previous approach are to "dmsetup $device"
 while the approach I propose is "dmsetup | grep $device".
