Replacing part of the boot artifacts is a common development use case, e.g. to load the kernel from the network, but otherwise boot the bootloader spec file as-is or to inject an initrd into an existing boot flow (e.g. rsinit to enable usb9pfs boot). This series adds a simple to use way to achieve that.
