- Merge some parts of IoInitSystem in the same main function instead of calling out to 10 external modules.
- Re-factor some code into smaller functions. - Don't create some Object Directories twice, since now ExpCreateSystemRootLink does some of them. - Add some failure paths to I/O Init. - Implement a function to mark the boot partition DO_SYSTEM_BOOT_PARTITION in order to better catch some bugchecks. svn path=/trunk/; revision=24552
