Oh. I thought it was (setting) the orientation that flipped it; does it actually have a different meaning when (querying) it? If so, my random screensaver mod (current version using pngshow) might rotate images 180° on the Kobo Glo or something. I need some testers... or more Kobo devices to test with (but I can't afford buying one of each so…).

Do you mean that there is an upgrade package on the backup/resert partition, which installs those files rather than copying the backup partition in its entirety?

The recovery partition is more or less a copy of the rootfs partition. It holds the original firmware and files; it has some extra files too, namely the script that actually performs the recovery.
It's true there are some files missing from the KoboRoot.tgz firmware upgrades, for example the device-specific bootup screen progress bar images? Not sure why they're not including those as well, it only saves 1MB or so. Not sure what else is missing either, I should check sometime.
But apart from such small details it's a full firmware image, so you can go any version -> any other version, you don't have to do incremental updates like 3.12->3.13->3.14->3.15. My old reader (iriver) had such an incremental system, it made for small update files, but it also made for bricks when people manually downloaded and used the wrong ones.

I would have expected it to just clone the backup partition using dd.

dd is only used to install bootloader + kernel into the area before the first partition.
If possible I'd not mess with the recovery partition. It's your insurance against bricks, unless you don't mind opening the device up to handle the SD card directly?
