[olpc-help] SD card usage per initial response.

[Steve Kay]

In light of the following are we to assume the SD card slot was
installed 100% for future development? A lot of work and filesystem
trickery does not sound inviting, especially if place in a childs
hands to go poof if XO is powered down (more likely used until battery
low suspends machine).

Simple answer is none.  Activities are installed to the olpc users dir
and the data is stored in the journal.  All that happens in /home/olpc
which is on the nand.

The complex answer is all of them.  With filesystem trickery you could
make locations on the the SD card show up as the /home/olpc dir.  Be
prepared for a lot work to make it happen, but its possible.

And a further note is that SD is still not safe if you suspend the
machine.  So if the SD card is mounted and you suspend the machine by
pressing the power button or closing the lid then it tends to corrupt
your SD card filesystem.
