So kpartx creates device maps, not just prints them, right?

Think of kpartx as "k-PART-X marks the spot" because it literally maps out where each partition lives so the kernel can find it, especially on loopback or virtual disk images. Here is my question for anyone who got tripped up on the graphical options: if the command runs happily over SSH with no display at all, does that tell you something about whether it needs any kind of XWindows environment?

C is it, kpartx reads those virtual disk partition tables and prints them out.
