Problems with Understanding Drive Order (6 replies)

Okay, so I was setting up a new Pink E02 and had everything working great... and then I plugged in a hard disk and the USB drive order changed. Boom, my boot disk became sdb1 and wouldn't boot. I thought I had taken care of problems with changing drive order by using the "LABEL=" syntax with the usb_root variable, but then I realized that the usb_load was directly referencing device 0:1... so I still had a dependency on sda1.

I see that Jeff's old uboot script sets up a scan of all of the USB drives to locate the correct device with the uImage on it and I could incorporate this scan in my variables. Is this the right way to fix this problem under newer versions of uboot by Bodhi? Or is there something I am not understanding? I can generally puzzle out scripting questions, but I'm not at all good with the internals of Linux booting.
