This is one of the best features of the Air-Bag Menu System. This option will cause the system to appear as if it has been rebooted from the hard-drive but in single user mode. All filesystems are mounted, including all data partitions. Administrative tasks can be performed on the system while in this state. The power of this feature is that if the system is not bootable, yet nearly functional, it can be in single user mode and make repairs and restore files that are damaged.
