Thanks, but did you test that it actually works in practice?

I strongly suspect that it still won't work.  According to
<https://wiki.archlinux.org/index.php/Fprint>, the 'pam_fprintd.so'
module needs to be added to the PAM configuration.

So, I guess we also need something along the lines of the following,
which is used in 'elogind-service-type' in (gnu services desktop):

                       ;; Extend PAM with pam_fprintd.so.
                       (service-extension pam-root-service-type
                                          pam-extension-procedure)

Would you be willing to take a look?  I think it would be embarrassing
to release Guix 1.0 with a documented service that has never been
tested.  What do you think?

      Regards,
        Mark
