The card in the SD slot is automatically mounted, and appears as a separate "Journal Icon" under the Journal Activity.<br><br>From here, you can copy Journal entries to the SD card or load Journal entries already on the SD card Journal into the host XO. It provides a means for backing-up Journal entries, and transferring them to other XO's.<br>
<br>It also serves the system administration functions mentioned, but system administration-type knowledge is required for that, beyond what a child is expected to know. System administration is not really meant to sound inviting to a child, nor is the OLPC initiative attempting to make system administrators of children. <br>

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

Simple answer is none. Activities are installed to the olpc users dir<br>
and the data is stored in the journal. All that happens in /home/olpc<br>
which is on the nand.<br>
<br>
The complex answer is all of them. With filesystem trickery you could<br>
make locations on the the SD card show up as the /home/olpc dir. Be<br>
prepared for a lot work to make it happen, but its possible.<br>
<br>
And a further note is that SD is still not safe if you suspend the<br>
machine. So if the SD card is mounted and you suspend the machine by<br>
pressing the power button or closing the lid then it tends to corrupt<br>
your SD card filesystem.<br>
