Abstract
A method for booting a computer operating system is provided. A boot loader is loaded from a first flash memory to a random access memory and executed. In one embodiment, the boot loader loads from a second flash memory to a random access memory an operating system file system image archive, installs the operating system file system image archive as a root file system, loads from the second flash memory multiple operating system patches stored separately from the base operating system file system image archive, and installs the multiple operating system patches over the root file system. In another embodiment, the boot loader loads and executes an initialization script that performs the operations instead of the boot loader.
