@poddingue Thank you for the feedback!
As I am typing this, I believe I've found the issue for autostart issues.
My rc.local:
[09:15 REDACTED]# cat etc/rc.local
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
touch /var/lock/subsys/local
sleep 300
/usr/bin/xe appliance-start uuid=00edfd41-1b01-f401-43cb-68201c6415c6
From the commented out section above we can clearly see that correct permissions need to be set on /etc/rc.d/rc.local, while my permissions got back to default values after upgrade, see below:
[09:16 REDACTED rc.d]# ls -al /etc/rc.d/rc.local
-rw-r--r-- 1 root root 556 Jul 29 16:17 /etc/rc.d/rc.local
I've mounted backup partition and they were properly set on 8.2.
I will make required changes and re-test in the upcoming days, not today.
In regards to "other-config:" CLI commands - colon-vs-equals, I will try do dive into this a little deeper and come back with more info.
