Sunday I was installing my new SSL/TLS certificates which I had received a couple of months prior to that time ...
I don't know what I'd been doing but it's far more fiscally responsible to place a credential for which you pay money in effect at the earliest moment feasible.
Suffice it to say that waiting to install a certificate loses you that time it covers while uninstalled. This may be multiplied by the number of certs purchased which in my case was four.
The install went well on the web server, so I thought.
The web stuff worked like gangbusters but the rdbms detected the new cert and reconfigured itself on the fly at that point in time.
This resulted in a load failure of the rdms at boot and I scratched my head then pondered a moment.
So ... I did a deep dive into the configuration files and manually fixed them.
The only linked stuff there was the demo mess supplied with the distro which I terminated with extreme prejudice and the errors went away.
The mail server was somewhat more convoluted without an apparent problem per se but appeared to be a file translation error that inserted some extraneous nonprinting character affecting the nested file logic. I couldn't "see" any error; but the command string interpreter was balking anyway.
So I copied the file from a backup location and edited it with the current cert data and voila it too straightened up and flew right.
The moral of the story is never put off something that needs to be done until you've forgot a lot of the specifics — which will have to be rediscovered on the fly.
