It looks like it doesn't work when using usb. I tried it on a regular internal drive and I can force it to do either ssd or spinning style boot using the pre-start script.

Also, how would you do debugging during the pre-start script? I tried echoing some stuff to a temp file, but it caused ureadahead to not start.
