Now I'm completely and utterly confused :-)
I put in the debug.sh script in place and edited the grub.cfg to add in the
systemd debug lines including the enforcing=0.
Here's the link to the output file
https://www.amazon.com/clouddrive/share?s=txDEjSfhRRspXGR4KioIa8
I tried the poweroff and it worked. I rebooted tried it again and it
worked. I rebooted again and tried the
echo 1 >/proc/sys/kernel/sysrq
echo r >/proc/sysrq-trigger
echo i >/proc/sysrq-trigger
echo s >/proc/sysrq-trigger
echo u >/proc/sysrq-trigger
echo b >/proc/sysrq-trigger
Just to see what would happen.
It started to do a SElinux relable and got about 20% before it rebooted.
Now the reason I'm utterly confused is that it got to graphical mode :-(.
I typed Ctrl-Alt-F3 to get to a virtual console and entered
poweroff
and this time the system did not power off, it reset and now I'm back in
rescue mode. Here's the link to the shutdown-log.txt file for this event.

When I was in the virtual console I ran ifconfig and it did not see any
network interfaces, it only showed the loopback interface.
