"/var/log/message" (an excerpt) showing Automount being stopped.

I may have been mistake blaming Gnome.  Or perhaps not.  I recently did an
update of Leap 15.1 using "Icewm".  And I ran into the same problem.  I have
attached the logs recorded during that session.

Search for "Automount" to find the relevant lines.  The few lines above suggest
that networking was being shutdown too.

I was using GDM for that system.  And GDM keeps its own active session with
user "gdm" which is apparently configured to sleep after an idle problem. 
Perhaps that is related.

In any case, I will do some more investigation to try to find out when this
happens.  I'll switch to using SDDM to see if that prevents it from occurring.

Maybe postpone looking hard at this until I have more to report.
