Title: Cross file system caching and synchronization

Abstract: A method for file synchronization during an operating system boot sequence between a client and a server. Upon initiation of the boot sequence, a mini file system driver is downloaded to the client. The mini file system driver is used to download the full operating system kernel. During a first phase of the boot sequence, file data and information for managing the file data generated by a first file system driver is cached. Upon initialization of the operating system, i.e. during a subsequent phase of the boot sequence, a second file system inherits the file data and information from the first file system driver. The second file system unloads the first file system driver and updates the data files.
