It sucks--but I suspect there's just not a lot of people updating their u-boot installation all the time (or at all ever). I'm not sure whether it's better to just provide the old u-boot or to figure out what exactly broke (the latter is probably gonna take quite some time). > In the end, I reinstalled a foreign distribution (that uses u-boot > 2017.01) and can SSH to the machine, but I haven't reinstalled Guix > yet.
