Is out of the box Lightning Node functionality planned by FutureBit or does anyone have a step by step guide for setting one up on it?
Yes, I believe it's planned.
I did create a guide, based on a fresh install of Armbian (the Linux distro also used by Apollo / which you get on the SD card images they provide), so it should work exactly the same on the latest version of 'Futurebit OS'.
