I did Step 2 option A and got my ninja.

I think you should consider one slight change to the instructions.
Step 4 reads:
- ./rage*.bin
This will take some time, just wait for the $ to show up so you know it is done.
I had the $ show up almost immediately, and I was suspicious about how fast that happened, but only waited a little while longer before quitting and restarting terminal. I had no #. I rebooted and repeated the first 4 steps, this time determined to wait a
long time for some other sign (perhaps a second $) and after a while "[+] forked 3801 childs" appeared, but I kept on waiting almost an hour for another $ that never happened. When I reopened terminal again I had my #. I suspect that the rooting process is finished when the forked childs line appears, not when a $ shows up.
