As near as I can recall, the builder image refuses to reformat things if it sees them already formatted, or something like that. So perhaps this was the problem here too.. dunno.

I think I will re-spin the bigdisk builder to just nuke everything each time unconditionally, if it doesn't so already. More dangerous, but it's pretty hard to mistakenly flash/run the bigdisk builder "by accident", so probably not much of a concern.
