Hi, Layne. Glad my changes helped.
It's not surprising that there are some remaining race conditions. I'm
afraid I can't remember whether I have this particular problem or not.
My variable settings shown by upsc are below.
I think the general plan should be to run the system on the UPS for as
long as possible, then shut it down with the shortest delay possible
that still allows for a clean shutdown of your system. If these times
are, say, 10 minutes and 10 seconds, then you only encounter the race if
the power happens to be off for an interval between 0:10:00 and 0:10:10,
which is quite unlikely.
Actually fixing all races would be better still, but I do not have a
good enough understanding of how my UPS handles the various settings to
be able to do that.
