Long story short: there was a bug fixed by 60a2d27.

I=E2=80=99ve tried your OS config in a VM.  Everything looks good: nsswitch=
.conf
is OK, and we can see that libnss_mdns.so is mapped into nscd=E2=80=99s add=
ress
space.

Yet looking up =E2=80=98jojen.local=E2=80=99 doesn=E2=80=99t work.  I added=
 some nscd debugging
like this:

           (nscd-service
            (nscd-configuration (inherit %nscd-default-configuration)
                                (debug-level 10))
            #:name-services (list nss-mdns))

/var/log/nscd.log shows warns about missing /var/db/nscd directory and
/etc/resolv.conf, which I added (with =E2=80=9Cdhclient eth0=E2=80=9D for t=
he latter),
to no avail.

Then I notice that even my config, which works on the bare metal,
doesn=E2=80=99t work in the VM.  I strace nscd in the VM to notice that it =
tries
to connect to /run/avahi-daemon/socket, which doesn=E2=80=99t exist.  This =
is
where I realize that my real root partition has /var/run as a symlink to
/run, which is why I don=E2=80=99t have the problem.  Pheeww.

Can you confirm that it works now?  :-)

Thanks,
Ludo=E2=80=99.
