This article is a stub. You can help the OLPC project by expanding it.
This page describes the Linux filesystem underlying the XO, particularly some unusual aspects of this implementation.
Store things you want to persist under /home/olpc

Example Treemap of the File-system
Joyride 2174 treemap
You can clearly see the two OS images that have previously been installed using olpc-update. /versions/pristine is the original data, /versions/run are hard linked to pristine (unless modified by the user). Top right is the actual running OS data (hard linked to one of the /versions/run blocks). /home/olpc stores all user generated data.
