This is where ARM gets icky:  There is literally a different boot
loader chain for almost every separate board.  One motivation
for building Crochet was to experiment with ideas for managing
that diversity.

I'll try to find time to tinker with the release(7) stuff and
see if there's any way the ideas I've been using for Crochet
might fit in here. 

Thanks for the pointer…

P.S.   Will you be at BSDCan?  GNN is trying to put together
a session at the DevSummit to talk about image building.
