Here's the INTERNAL.txt mostly copied from the sample one.

Attached is the error log, which is doing something different now. I removed partitions from the card, made it one big FAT partition instead. It doesn't do anything to partition it either... and I should mention I am running as root...

The initfs seems to have installed OK. I get the boot menu. Actually the first time it worked but never really repartitioned either - my stuff was all still there. It must have overwritten something in my existing ext2 partition, for some reason. No idea why it actually booted successfully, unless it didn't and failed back to the flash - but it seemed to work.

I'm in rescue mode right now. I'll be back once I'm running again.
