Linutop Persistence mode
"By default the Linutop system adds a third layer. This layer is the second partition provided on the USB key. It is mounted rw (read/write) on the /home directory. So when you will write in your personal directory (/home/linutop), data will be written on the key, and not in the memory. That's why documents and personal settings can be kept after a reboot."
How does this work on the Linutop2? Is the flash disk similarly partitioned?
Yes, this is exactly the same configuration.
