Clarif #2: this RPi3 is connected to the Internet via Ethernet.

Clarif #3: This most recent Shutdown/Reboot tests was run almost 10 times
over the past 2 hours, by typing "reboot" at the prompt, as root.  Also,
just to confirm, the same reboot was confirmed a couple times from
IIAX/XSCE's Admin Console(*).

Conclusion: apt-get or "cd /opt/schoolserver/xsce; git pull" similar must
have applied some changes in recent days, as the shutdowns have now
reverted to the Linux-style stream of small messages scrolling up the
screen.  Until today, the shutdown screen was entirely different (a black
screen with a single short message at a time in the bottom-left, in a
fancier white font, such as the notorious "*Deconfiguring network
interfaces*").  Shutdown still takes almost-80-seconds longer than it
should, regardless if "*Remove slice system-systemd\x2drfkill.**slice.*" is
a more meaningful/specific hint as to what's going on?

(*) Earlier tests last week had generally been triggered by the "REBOOT
Server" button within IIAB/XSCE's Admin Console (http://box/admin).  Still
this seems to make no difference at all (how reboots are triggered, from
the command line or from IIAB/XSCE's Admin Console).
