Yeah, os-with-u-boot is not really useful right now - it would be nice to have something like it but as long as upstream u-boot doesn't include the respective installer themselves we can't be generic enough - or we'd have to depend on buildroot and genimage. So don't worry about it for now. I've applied this patch as commit 74e35e8c94193a03cb1db61934340540ce0884a3 to guix master. Thanks!
