Claim:
A computing device comprising: one or more processors; one or more storage media coupled to the one or more processors; pivot logic stored in the one or more storage media and executable by the one or more processors, wherein the pivot logic is configured to cause the one or more processors to: execute a pivot process during a first boot of an operating system (OS) on the computing device, wherein the pivot process is the only process running when performing modifications to a file system on the computing device, wherein during execution the pivot process causes the one or more processors to: replace a current set of files in the file system with a new desktop image, wherein the new desktop image presents a complete view of the file system; wherein a prefetch set of files is included in the new desktop image, but other files are represented in the complete view of the file system by file metadata that is included in the new desktop image; wherein the prefetch set of files includes a smallest subset of files, in the new desktop image, that is needed to boot the computing device without requiring retrieval of additional files; terminate the first boot and invoke a second boot that is executed based on the prefetch set of files included in the new desktop image.
