Abstract

Methods of upgrading a kernel image of a remote computer are described. The method comprises, during a first connection between an update computer and a remote computer, storing a kernel version identifier of the active kernel image of the remote computer; storing active boot partition information comprising the active kernel boot partition of the remote computer; setting the active boot partition of the remote computer as a safe boot partition; storing a second kernel image at the remote computer, wherein the second kernel image comprises a second kernel version identifier; setting the remote computer to boot from the second kernel image; rebooting the remote computer; and, during a second connection between the update computer and the remote computer, marking the second kernel image as a safe kernel image if the active kernel version is the same as the second kernel version identifier.
