Do i understand correctly that the bootstrap-tarballs can be cross-compiled and tested (to some extent) in a qemu-system-riscv? Or does this *have* to fail (by Guix's design) due to it not being bootstrappable?

I've been thinking about getting a HiFive Unmatched for a while and getting the hardware makes working on it a bit more exciting! Do i understand correctly that this machine would then be used to build Guix packages and serve them? I.e. a worker on ci.guix.gnu.org? Have a nice week! gabriel
