So I have a disk image, and I'm trying to convert it to a raw image.  It never gave me grief before, but when I try to do the conversion I get an error:

sudo qemu-img convert -f qcow2 -O raw ./instance-0000000a/disk jenkins-attempt-1
> qemu-img: error while reading sector 10203136: Input/output error

Alright, so I checked the disk to see if I got the same error with qemu-io:

sudo qemu-io -c "read -v $((10203136 * 512)) 65536" ./instance-0000000a/disk

And that gives me:

Spree Checkout Fakery

We want to use spree to manage inventory/products, but our app uses funny money and needs to override checkout.

Ordering a product is a one-step process. Click a button, order fulfilled. My plan is as follows:

On button click:

• Create a cart.
• Add the product to the cart.
• Specify my own address bits to handle fulfilment.
• Push the order through all of its state machine, step by step. I won't skip any, I'll just do them all in one action. (this will be in a plain ol' ruby object that handles all of this)

module Spree
  class Gateway::FunnyMoney < Gateway
    attr_accessor :test

    def provider_class
      self.class
    end

    def preferences
      {}
