BTW, the initramfs standard allows for multiple cpio archives, so in
principle, one could have an "addon" images.  That's useful, because
we want kernel modules in the the initrd-$KVER.img, but we could have
a generic initrd-rescue.img that is loaded after it.
 
Caveat: I haven't tried this, and don't know whether it actually works
with current kernels.
