I just tried it out, and you're right. We should see some barebox 
messages, and then some systemd startup messages, followed by a login 
prompt. However, the system does not even seem to start the barebox 
bootloader.

I'm not sure how to debug this, but you could try to work-around this 
bug by copy /boot/zImage from the second partition on the SD card to the 
boot partition, and changing "kernel=barebox.bin" to "kernel=zImage" in 
config.txt.

This is one of my old repos which I used as a playground for DistroKit 
when working on my master's thesis. It is a fork of an old version of 
the official DistroKit Git repo. Back then, I only had access to a RPi1, 
so I used platform-rpi. Also, this was before platform-rpi and 
platform-v7a was recently overhauled in DistroKit in July.

RPi 1 should work with platform-rpi, RPi 2 should work with 
platform-v7a. RPi 3 should in theory also work with platform-v7a, but I 
think no one has come around yet to testing that...
