The (lset-difference =E2=80=A6) expression above is equal to =E2=80=98%base=
-packages=E2=80=99,
because the third argument is a list of symbols whereas the second one
is a list a packages (so these two sets are disjoint).

You probably meant:

        (lset-difference eq? %base-packages
                         (list libinput avahi bluez))

I don=E2=80=99t know the answer to your initial question though.

Ludo=E2=80=99.
