Debugging Tips

 * Debug user-space initialization:
 * If you get a panic - "not syncing: Attempted to kill init!" it can be for many different reasons. Try setting CONFIG_DEBUG_USER=y in your .config and pass 'user_debug=255' in the kernel command line. That will give you a more verbose output about why user space programs crash.
