Hello Joshua,

Thanks for this new revision! It's really nice to follow your live
coding sessions. I think it can be very valuable for newcomers willing
to dive into Guix internals.

                                                                   ^
                                                                   efi-raw
> +@code{compressed-qcow2} or @code{iso9660}. In the future, it could be
              ^
              qcow2
              
The supported image types list is now longer, so you could add "for
instance". We could also specify that "raw" designates disk-image that
can be copied as is on the installation media.

You mean @file{gnu/system/images/novena.scm}, right?

Since recently "raw" has been renamed "efi-raw".

Nice example. However, we generally prefer using inheritance. That would
give:

--8<---------------cut here---------------start------------->8---
(use-modules (gnu system)
             (gnu services linux)
             (gnu system images pine64))

(let ((base-os pine64-barebones-os))
  (operating-system
    (inherit base-os)
    (timezone "America/Indiana/Indianapolis")
    (services
     (cons*
      (service earlyoom-service-type
               (earlyoom-configuration
                (prefer-regexp "icecat|chromium|firefox")))
      (operating-system-user-services base-os)))))
--8<---------------cut here---------------end--------------->8---

WDYT?

Thanks,

Mathieu
