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.

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.
