The File system
The onboard flash has been divided into three partitions (boot, root (/) and /var). By default the
root partition is mounted read-only for added data security, to mount it read-write type
mount –n –o remount,rw /
The /var partition is read-write and can be used for storing application data which must persist
across reboots. The /var partition also contains users’ home directories. In addition a 2 Mbyte
ram disk is mounted on /var/tmp for temporary files -- these will be lost after a reboot.
