These instructions are not just outdated, they are utterly destructive. :-/
Using the makesd script from /latest against the /latest directory, you
do get a kind of working system; running from my 1 GB SD it wasn't even
upgradable due to lack of space, but that's not the actual problem:
Running ./flash-nand will clear the nand but bark upon the new system
not fitting into the memory! Consequently, the multiboot nand menu is
gone then …

There should at least be a warning on that page — and the script should
at least check the size before erasing the nand.

I did not find any information which of these files would be the "right"
one for my gta04 board (or how to determine the board revision by
software anyway).
The file 20140728-gta04b3.dd being 1056964608 bytes in size, it should
fit onto a 1 GB SD card?
Could you elaborate a bit on "unpack the right .dd image onto a fresh SD
card" for someone who never did that before? :-)
