Any operating system stored on an SD card may eventually fail if used for long periods of time. To reduce these risks, you can make your SD card read-only. Open the raspi-config tool with the following command:<br /> $ sudo raspi-config<br /> Navigate through the menu system as follows:<br /> #Select Performance options<br /> #Select Overlay File System<br /> #Confirm that you would like to enable the overlay file system<br /> #Confirm that you would like to write-protect the boot partition<br /> #Confirm reboot<br /> This whole process may take a few minutes to complete.<br /> &lt;br&gt;&lt;br&gt;<br /> <br /> If you need to enable access again to carry out an update or adjust your scripts, SSH back into your Raspberry Pi and run this command to allow write access temporarily:<br /> <br /> $ sudo mount -o remount,rw /boot<br /> You can now carry out any work required. Another reboot will revert your SD card to a read-only state.</div>
