The only modifiable parts of fs are /opt1 and /Data. You can write to /tmp, /var and /etc, but all changes will be lost on a reboot. So, we don't have any way to change the scripts or programs with just the USB copy interface. However, I have some good news.
1) I can dump the original flash partitions with a slightly modified ebook.py. This gives me the original cramfs images that I can edit to my heart's content.
2) I've discovered functions used for updating of the flash and figured out most of their parameters. Now I need to add them to ebook.py and maybe try reflashing the same image back... that shouldn't break anything, I hope. Of course, the best would be to wait for an official updater and try to hijack the updated firmware binary as it was done with Librie... but who knows how long we'll have to wait for that.
