Well, I guess we could get a little more creative with the image.
I've kept to really simple... Right now the only difference between
the dd/microSD image with the dd/flasher is one file in the boot
partition..

/boot/uboot/flash-eMMC.txt

https://github.com/beagleboard/image-builder/blob/master/scripts_device/boot/am335x_evm.sh#L56

Otherwise the biggest cpu hog was actually the screensaver. (xorg/lxde
wasn't too resource intensive..)

Which i've now disabled by default:

So when i push out new image this week, it should shave a few more
minutes.. (even without that change it's still not the 45 minutes it
took Angstrom.. ;) )

Do we want it to "halt" ?  I wish we could "eject" the microSD, as if
we halt, the user is just probably going to hit the power button and
the flash starts all over..
