It's not hung, it can just take a long, long time to run all the init scripts (less than a day, but maybe not much less). If you're willing to wait they should all complete and get you to a log in prompt. You'll want to make sure you change fstab and the root password in your image before hand. There may be some other small tweak you'll need to make to the image, but I don't know off hand what it would be. It's fine to replace the init scripts with something that runs your benchmark and that will speed up boot significantly.
