## Making changes to the system after setup
The setup process configures the Pi with read-only file systems for the operating system but with read-write access through the USB
interface. This means that you'll be able to record dashcam video and add and remove music files but you won't be able to make changes
to files on / or on /boot. This is to protect against corruption of the operating system when the Tesla cuts power to the Pi.
To make changes to the system partitions:
```
ssh pi@teslausb.
sudo -i
mount / -o remount,rw
mount /boot -o remount,rw
```
Then make whatever changes you need to. The next time the system boots the partitions will once again be read-only.
