After some discussions got started over in the Upgrade thread on changing the SD card to a different format than the default FAT32 I thought I would move the discussion over here.

It looks like the ability to mount non FAT32 formats was there at one point, and has now been commented out. |

After modifying some files you can pack them again into "KoboRoot.tgz" (you have of course to preserve the path of each modified file, but there is no need to include all the other files). Copy then "KoboRoot.tgz" to the folder ".kobo" of the reader. After unplugging the reader, it will copy the content of "KoboRoot.tgz" to the system partition. Confer the paragraph "The Kobo upgrade mechanism" of "Hacking the Kobo Touch for DUMMIES". This part is valid for Glo too.
Word of caution: Preserve lower and upper case of file and path names (e.g. udev, not uDev).
If you mess things up, you might have to factory reset the reader. If you have a lot of annotations and highlights, you might consider making a back up of .kobo/KoboReader.sqlite. |

I have looked at the two files usr/local/Kobo/udev/usb and usr/local/Kobo/udev/sd, both have the commented out section that PeterT refers to. I assume that one refers to the internal microSD cards FAT32 partition, and the other to the external microSD card, do you know which is which?

/mnt/onboard appears to be used for the partition that is accessible to us normally, and /mnt/sd to the external SD card.
I think that this section

should be similar to the code in /usr/local/Kobo/udev/sd |
