> I have trouble getting the syntax right to delete avahi and wicd from

The correct syntax would be:

  (operating-system
    ;; =E2=80=A6
    (services (remove (lambda (service)
                        (or (eq? (service-kind service)
                                 wicd-service-type)
                            (eq? (service-kind service)
                                 avahi-service-type)))
                      %desktop-services)))

As David notes, =E2=80=98%desktop-services=E2=80=99 is a list of service ob=
jects.  To
remove elements from a list, the right procedure is =E2=80=98remove=E2=80=
=99 (info
"(guile) SRFI-1 Filtering and Partitioning").

I=E2=80=99ve added this example in commit 5d94ac5.

HTH!
