I recently added a workaround to the OFW USB mass storage code so it can
handle a particular USB-to-MicroSD adapter that was causing problems.
The workaround required some major surgery to the code, specifically to

Should we tell Uruguay to delete the files in that dir after every boot?

The filesystem layout for the tuxpaint activity has a lot of boilerplate
that contributes to it taking up a lot of space on NAND.
In some NAND images from Uruguay that I analyzed today, over 5000
directory entries - nearly 50% of the total number of dirents in /home -
were from tuxpaint.

JFFS2 does automatic compression so every write invokes zlib

savings. But JFFS2 can behav

I can make a q2d12 with the fix for 6291. The fix is extremely low risk
- just a change in one number that tells how far to search for
additional nodes in a partially-written block.
The only reason why I haven't made a q2d12 already is because I can't

You don't really need the entire olpc.fth - the following lines should

I suppose that OFW could reset the wireless to turn it off and then do
some chipset configuration hack that would make that USB port
disappear. I'm just guessing though; I haven't studied the 5536 manual
