 Installing is, in principle, simple.

 Reboot!

+After rebooting you can run **list-pins.py** (see below) to verify the new mappings.
 
 If you have errors rebooting (maybe a corrupt file if you rebuilt it etc..) you need to either boot using a USB serial adapter on the console pins and select the recovery image,  or, in grub, edit the command and revert to the generic `/boot/dtb`. 
 As a last resort you may have to remove the SD card, mount the `/boot` partition and edit `grub/grub.cfg` there.
 * !! The 'default' dtb supplied by ubuntu should always be softlinked as `/boot/dtb`, so putting `devicetree      /boot/dtb` in grub in place of the custom `.dtb` should work and is predictable (no version numbers etc).
