That was my gonna be my next step, I ended up just grabbing ash, libc,
ld-linux, ifconfig, and route off of tom's root-boot (his binaries are
amazingly small...).  Since I've gotta get this thing up this weekend, I
figured I'll spend the time to debug the library problem on another related
project that's going in my car.  I've got more time on that one, since it
doesn't have a deadline. :)  Speaking of a static ash, the ash source I
pulled down refers to some bsd.h file or something like that.  As a result
of that not existing on the danny machines, it didn't compile.  Is there
some ash source laying around somewhere that does compile out of the box
(or tarball, as the case may be) on what I think is a regular linux box?

I need to learn more about how to use gcc and specific libraries.  Does
O'Reily make a book that covers that? :)
