The philosophy of the configuration file changed quite
a bit between even
7.8 to 8.0, let alone 7.6 to 8.2.
Unlike before, there's hardly anything that's actually
required to be present
in the config file - nearly everything is built in
as a default, and so the
only thing you need to do is override whatever you

the defaults, and this is usually a very small list
And so a 7.6 config file will invariably have a lot
of extraneous stuff in it.
When I shifted over to 8, I wound up reconstructing
the config by taking the
8.0 default and adding only the local customization
such as startd_cron and
policy expressions via the config.d, and discarding
else that had been in the 7.6 and 7.8 config files.
Are your exec nodes upgraded, or still running 7.6
at this point?
The error indicates that the daemon that's supposed
