Meta is at the end. Gunzip will give you a warning and ignored it when
expanded.

First byte of the expanded image is the disk sector 0. It is a normal disk
image with partitions. I didn't test EFI, which might use GPT but the other
one is simply a DOSMBR partitioned disk.

The default size is about 256MB (or is it 128?). Just dd it to something a
little bit bigger and let it run.
