Subject: kernel-initramfs: A recipe to build a kernel with linked in
 initramfs. * First builds ${KERNEL_INITRAMFS} in cpio.gz format, then stuffs
 it into kernel as specified by virtual/kernel, deploys to deploy dir, and
 packages kernel-image (the package would overrite previously built
 kernel-image package w/o initramfs, so caveat). * kernel-image packaing
 actually requires PKGPV/PKGPR support, to be RFCed.
