Hello Jesse,
-> Which board did you get working with guix system (banana pi m2u, novena,
beaglebone black, pine64-plus, etc.)?
-> Did you build natively or cross-build from a different system?
-> What version of guix did you use? (what did guix describe say?)
-> If the board you got working can boot from an internal (emmc) or external
(microsd) drive, which one did you get working?
-> Would you mind sharing the operating-system definition that was successful?
The situation is slowly improving. Since recently, you should be able to
build a barebones image for pine64 lts this way:
--8<---------------cut here---------------start------------->8---
guix system disk-image -t pine64-raw os.scm
--8<---------------cut here---------------end--------------->8---
with os.scm that looks like:
--8<---------------cut here---------------start------------->8---
(use-modules (gnu system images pine64))
pine64-barebones-os
--8<---------------cut here---------------end--------------->8---
Note that this very image is also build by the CI and available here:
https://ci.guix.gnu.org/search/latest/image?query=spec:guix-master+status:success+system:x86_64-linux+pine64
You should be able to flash this image on a microsd and directly boot
from it.
I will try to improve the documentation accordingly, but until then you
can also read this:

Thanks,
Mathieu
