That's not what I was expecting from comments made to me elsewhere. They didn't say how the partitions had changed, but the warning for using the the Libra 2 update on the older devices implied it would have.

Has anyone looked at a Sage? Or Elipsa for that matter?

The recoveryfs (factory reset image) is larger with 384MiB as it contains the full rootfs twice (a minimal image to boot factory reset environment, plus the full rootfs the kobo normally uses) and also contains the data the user partition will be originally populated with (welcome message manual empty database and what not).

So all in all it uses 24MiB (bootloader, kernel) + 256MiB (rootfs) + 384MiB (recoveryfs) and at the end of the card it wastes another ~16 MiB for nothing whatsoever, probably to take into account that SD cards are not always exactly the same size. That leaves 29152 MiB to the user.

There should be very little write activity in the rootfs from day to day use, wifi network credentials are stored there but not much else. So there is no problem with reading books, all that should be happening on the user data partition (and in RAM naturally)
The warning was that there would not be space left to unpack some larger files. It came up because I tried it on my Aura H2O and had about 29MB free.
