I looked recently at this tutorial: https://guix.gnu.org/blog/2017/porting-guixsd-to-armv7/
However, it strikes me: maybe there's another nice approach? Would it be nicer to just make an image that the user boots into directly on the beagleboard, if it's going onto a microsd card anyway, rather than building an installer image? I haven't tried it yet but can't think of a good reason it wouldn't work. Has anyone tried that? Side note, a RISC-V Beagleboard SoC is coming. I suspect that might be very good helping us start ramping up getting Guix very usable on RISC-V: https://arstechnica.com/gadgets/2021/01/seeed-and-beagleboard-team-up-to-provide-a-new-risc-v-based-linux-pc/
