PW2 Boot and shutdown dependency graphs

Hi! I've been playing with my new PW2 and plotted a neat svg of boot and shutdown upstart dependencies with links to original scripts.

I figured the lone services at top left corner are the ones that are not used in the respective sequences. Also, I don't know if vnc leftovers are from usbnetwork or lab126 -- all I know is /usr/local/bin has nothing apart from usbnetwork.sh and my cross-compiled binaries in it.

Hope this can be useful for anyone.
