Just as a heads up, in the DM any difference between a partition and a whole 
block device (also between different interfaces for disks) is hidden from any 
user code (code other than the one keeping track of partitions/disks, that 
only uses such information to determine whether to scan for partitions), you 
only get some object that can read/write blocks if you ask it nicely, and you 
have to make do with that (if you need more then you're probably doing 
something wrong).
As a result, there is no notion of partition number, and the string you are 
patching up here (along with many others, due to unification of disk 
interfaces) is changed.
