Interesting idea. I had a look in the firmware. In etc/init.d/rcS, I find:
Code:
dosfsck -a -w /dev/mmcblk0p3
mount -t vfat -o iocharset=utf8 /dev/mmcblk0p3 /mnt/onboard
rm -rf /mnt/onboard/fsck*
rm -rf /mnt/onboard/FSCK*
rm -rf /usr/local/Kobo/db.tgz
And in /usr/local/Kobo/udev/sd:
Code:
dosfsck -a -w $DEVNAME
mount -r -t vfat -o shortname=mixed $DEVNAME /mnt/sd
But, these are unchanged since at least FW2.4.0. So that doesn't explain why the change in behaviour with FW2.5.2.
Removing these lines would be a good test. As would changing to ext3. Someone has done that recently, so it is possible.
