I've been over the code for partprobe and pyparted and they both do the same thing (they use the same code). They tell the kernel about the partition, but it seems to be asynchronous as to when the kernel gets around to making the device node. I thought maybe udev could help me out because it may be listening to the same "events" or whatnot that would cause the device node to get created.
