(Unrelated, but I personally find it more convenient to have only core
packages in the global profile, and then have the rest in user
profiles.)

The culprit is the =E2=80=98mingetty-service=E2=80=99 call above: since it =
uses a #:motd
different from that used in the other =E2=80=98mingetty-service=E2=80=99 ca=
lls in
%base-services, the thing tries to create a different pam.d/login file
for it, but that fails because there=E2=80=99s already a pam.d/login file.

The workaround is to write:

    (mingetty-service "ttyS0"
                      #:motd (text-file "motd" "
This is the GNU operating system, welcome!\n\n"))

Since this is the same motd as the other mingetty services, everything
is fine.

This is of course unsatisfactory.  The more general issue is that
service procedures need to be able to share state/configuration info,
which I hope we can fix soon.

Thanks,
Ludo=E2=80=99.
