Well, by specified OSBundleRequired "Root" you're telling the system that you have to be started in order to mount the root file system. This guarantees that you won't be able to read the file system to get your configuration parameters. At this point you'll have to get your configuration parameters via pre-boot mechanisms, which is kinda ugly (and outside my area of expertise).
