Oops, I spoke too fast: “make check-system TESTS=basic” shows one
problem, which stems from this:

--8<---------------cut here---------------start------------->8---
(define (operating-system-shepherd-service-names os)
  "Return the list of Shepherd service names for OS."
  (append-map shepherd-service-provision
              (service-value
               (fold-services (operating-system-services os)
                              #:target-type
                              shepherd-root-service-type))))
--8<---------------cut here---------------end--------------->8---

This procedure needs to be adjusted because the value of
‘shepherd-root-service-type’ instances is no longer a list of
<shepherd-service>.

I suspect ‘guix system search’ and ‘guix system shepherd-graph’ are
affected as well, though I didn’t check (“make check” should catch it, I
think.)

Could you take a look?

TIA,
Ludo’.
