Hello, this is due to recently added functinon to detect missing modules
in the initrd: <https://debbugs.gnu.org/30629>.

To fix it, you can use 'initrd-modules' instead of the 'initrd' field in
the 'operating-system' record.

This '#:extra-modules' usage is deprecated by the newly added
'initrd-modules' field in 'operating-system'.  For example:
<https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/system/examples/beaglebone-black.tmpl#n19>

Well, the guix info manual did got updated, but currently 'guix pull'
won't bring it, for reference: <https://debbugs.gnu.org/22629>.
