Ok, thanks, so you have a place to store user space images.  This thread got me
wondering what you were going to do long term about user space.  I was starting
to think as a space saving measure, that you were building your app into the
kernel or something.

FWIW, I think Uboot has a pretty robust mtd infrastructure that would allow you
to store a initramfs image there for use if you were interested in exploring
that route.
