[yocto] new system booting directly to halt

Chris,
Thanks for the suggestions. The system is based on SystemV and uses the
old school init scripts.
I rebuilt my kernel with init=/bin/sh and I can get into the system now!
The thing is, I don't see anything in /proc, and only /dev/null exists in
the /dev directory. I don't know if the lack of meta filesystems is due to
me skipping an actual init, or if I've buggered up something in my kernel
configuration.
This continues to be the world's most secure box, but I feel like I'm
making progress on that.
