Yeah, I end up using strings a lot myself. Next update I'll throw the
generator/boot.cmd template into /boot/uboot for easier tinkering. Long
term goal is to move to uEnv.txt, but that won't help systems with
built-in uboots that don't support it (trimslice).

As mentioned elsewhere in the followups this is because there are two sd
readers on a trimslice and you're using the mmc1 location. Perhaps for
trimslice there should be an mmc0 and mmc1 image? Once I merge
trimslice/panda images that might follow.

Earlier images used root=/dev/someplace, but using root=LABEL=rootfs
means fewer boot.scrs are (and less editing is) necessary. The right
answer probably is a randomly generated UUID per image. I'll consider
adding this next, unless David Marlin gets his lorax images all set
before I get to it. They're the real plan. Thanks again!
