Access to nongnu channel

[Timothy Washington]

I have created this guix system configuration (minimal working example)
with an "operating-system" declaration in *system.scm*.

(use-modules (gnu)
             (nongnu packages linux))

(operating-system
  (kernel linux)
  (firmware (list linux-firmware))
  (host-name "guix")
  (timezone "America/New_York")
  (locale "en_US.utf8")
  (bootloader (bootloader-configuration
                (bootloader grub-efi-bootloader)
                (targets '("/boot/efi"))))
  (file-systems %base-file-systems)
  (users (cons* (user-account
                 (name "user")
                 (group "users"))
               %base-user-accounts))
  (packages %base-packages)
  (services %base-services))


Note that there's an accompanying *channels.scm* file that provides the
"nongnu" packages.

(list (channel
        (name 'guix)
        (url "https://git.savannah.gnu.org/git/guix.git";)
        (introduction
          (make-channel-introduction
            "9edb3f66fd807b096b48283debdcddccfea34bad"
            (openpgp-fingerprint
              "BBB0 2DDF 2CEA F6A8 0D1D  E643 A2A0 6DF2 A33A 54FA"))))
      (channel
        (name 'nonguix)
        (url "https://gitlab.com/nonguix/nonguix";)
        (introduction
          (make-channel-introduction
            "897c1a470da759236cc11798f4e0a5f7d4d59fbc"
            (openpgp-fingerprint
              "2A39 3FFF 68F4 EF7A 3D29  12AF 6F51 20A0 22FB B2D5")))))


But trying to reconfigure my guix system with this command, gives the
following error.

$ sudo guix system reconfigure system.scm
guix system: error: failed to load 'system.scm':
ice-9/boot-9.scm:3330:6: In procedure resolve-interface:
no code for module (nongnu packages linux)


I took this approach from David Wilson's guide
<https://systemcrafters.net/craft-your-system-with-guix/full-system-install/>
when
first installing the system. And other's have come across the same issue...
But the `(nongnu packages linux)` module is definitely there (ref
<https://gitlab.com/nonguix/nonguix/-/blob/master/nongnu/packages/linux.scm?ref_type=heads>).
And I have pulled the nonguix channel before using it.

guix pull --channels=channels.scm


But the `guix system recofigure` command doesn't see it. And it's not clear
to me where all the "nongnu" packages agot installed. They are not in
`/gnu/store/`.
What am I missing here? What is the root cause of the error? And how do I
make those external channels available?
