From: Adrian Freihofer <[email protected]> Generate a helper for NFS-enabled IDE SDK images that exports the rootfs with runqemu-export-rootfs and serves the deploy directory over HTTP. This allows real hardware targets to boot the generated rootfs and retrieve the kernel from the deploy directory over HTTP.
For some use cases like u-boot with wget command built-in this helper is expected to cover the typical scenario. For other use cases the generated script at least provides a starting point and can be adapted as needed for other scenarios.
