Oops, didn't see this until today because this darn mailing list mangles
the reply-to header. *shakes fist*
Currently all of the tools check by trying to open the expected device
name. If they have different ideas of what that is, the check fails to
find the existing instance. It is looking to me like the way to fix
this is to patch dmraid and libparted so that they conform with the
kpartx and "linux since the dawn of time" method of only adding the 'p'
if the previous character is a digit.
