Correct.

About firmware upgrading: overwriting the "normal" partition with an image file, or extracting KoboRoot.tgz to the root is exactly the same thing in theory. So why firmware packages contains KoboRoot.tgz AND image files?
The uImage is 1.8MB and the KoboRoot.tgz is over 87MB. Hopefully there is something useful in that 87MB. Unless they have a really, REALLY good compression algorithm.

The uImage file is just the kernel. Everything else, including all the code for the Kobo applications are in the rootfs.

I suspect image files is the upgrade method of Mini, Touch and Aura HD. On the contrary, file coping is the Glo and Aura method. What a mess.
NO. They all use EXACTLY the same code to do this. The contents of KoboRoot.tgz is identical across all the devices except for the fonts and pictures. The uImage and uBoot files are different for the different devices.

Can you link me the multi-touch kernel installer?
I can't point to an "installer" as it uses the same method for installation as the firmware packages. But https://www.mobileread.com/forums/sho...d.php?t=232431 is where the kernel is available. When you open that file or the uninstall file, you will see an extra uImage which has the PCB for the Glo.
