Thank you for the response Luca.

I had to think on this one for a while.

In the case where a /dev/mapper device name ends in number, there exists 
more than one way that each partition will be named.

Command   Sample Partition #1 Name in /dev/mapper Directory
-------   -------------------------------------------------
dmraid    isw_cjbdddajhi_Vol01
kpartx    isw_cjbdddajhi_Vol0p1

Based on the fact that there might be more than one name, I assume that 
more than one partition minor number will be required.  Using this 
logic, libparted would the be tool that would need to handle this situation.
