On further inspection...

When I build my image, it creates a kernel with initramfs in the deploy directory:

    zImage-initramfs-3.14.39-r22b+gitrAUTOINC+ba552b4bc7-machine-20150428061518.bin

However, the rootfs image includes the kernel _without_ the initramfs in its /boot directory.

I'll investigate to see why.
