Abstract
The system and method described herein may upgrade kernels in cloud images deployed in cloud computing environments without having to rebuild a machine image that contains a root file system for the cloud image. For example, the cloud image may include a ramdisk that compares the kernel booted in the cloud image to the root file system to verify whether the machine image contains a directory hierarchy matching an operating system release for the kernel. In response to the machine image containing the matching directory hierarchy, the root file system may be mounted for execution in the cloud computing environment. Alternatively, in response to the machine image lacking the matching directory hierarchy, the ramdisk may dynamically create the matching directory hierarchy and inject modules that support the kernel into the root file system prior to mounting and delivering control to the root file system.
