Worse, I think the name /init has been burned by people using it... that 
whole thing wasn't phased very well.

My current thinking is to call it /kinit in the patch, and AT THE SAME 
TIME add a patch to the kernel to call /kinit if it exists.  This means 
kinit should finish by calling /init if it exists (this is a real issue 
if part of the initramfs comes from the kernel image and part 
externally), otherwise do a run-init equivalent and spawn the real root.

This is probably my #1 priority for next week.
