Hey, thanks for taking them for a test drive!

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!
