"Déjà vu" all over again, eh? http://en.wikipedia.org/wiki/Déjà_vu
"the experience of feeling sure that one has already witnessed or experienced a current situation, even though the exact circumstances of the prior encounter are uncertain and were perhaps imagined"

BTW, this is a sign of not enough sleep ... or your connection to "The Matrix" has been hijacked.

Although I did not study extended partitions in any detail, this is sort of how they work.

You can only have 4 primary partitions. If you set one or more of them to an extended partition, then you can put multiple logical partitions inside the extended partitions.

I suspect that treating partition 4 as a block device and giving it 4 more primary partitions was an easier hack than adding support for extended partitions and logical partitions inside them, and amazon wanted these things ready in time for the Christmas shopping season.

Why they did this, but then did not USE any extra partitions inside the inner partition table, is the *real* mystery -- perhaps for future expansion.

It looks like you COULD put more partitions on the "inner" block device and they would survive startup (but perhaps not a factory restore). This would let you shrink the vfat partition and add an ext3 partition after it. But WHY would anybody EVER want to do THAT?
