Abstract
A method for discovery of a root file system that includes obtaining a tag corresponding to a boot image for an operating system, identifying, by a boot loader, a location of the boot image having a predefined value matching the tag, loading a kernel of the operating system retrieved from the boot image, and transferring execution to the kernel, wherein the boot loader provides the tag for the location to the kernel. The method further includes identifying, by the kernel, the location of the root file system based on the tag provided by the boot loader, and executing the operating system on a processor using the root file system identified by the kernel.
