Abstract
An upgrade method for a Unix or Unix-like operating system, a server, and a cloud-based system include operating a server with an old operating system with a partition structure for media, wherein the partition structure includes a root partition and a usr partition; copying media to the root partition and the usr partition associated with a new operating system while the old operating system is operating; rebooting the server with the new operating system set to load; and subsequent to the rebooting, making the root partition persistent using memory and the usr partition persistent using a NULL file system.
