Thanks anon, but I couldn't make that work. I just ended up throwing this slightly modified snippet from the link I posted between use-modules and use-service-modules in my config:
(define (default-extra-linux-options version)
`(;; https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00039.html
("CONFIG_DEVPTS_MULTIPLE_INSTANCES" . #true)
;; Modules required for initrd:
("CONFIG_DEBUG_INFO_BTF=y")))
And now it's building. We'll see what happens in 6-7 hours kek.
