I've been wanting the ability to take a kernel image and add/replace an
initrd to the end of it after it is built and remain a single "image"
that you can then sign/copy/whatever.  You can't do that today due to
some static variables in the initrd image.  I started to hack it up a
while ago, need to carve up some time to revisit that to fix this issue,
which should make some of this easier.

sorry for the digression,
