For example, an apache update MAY require that I first check what it will do to http.conf.

NOT ON RHEL/CENTOS

there are no major upgrades with changing API/ABI/Config that is why it is called "enterprise distribution"

I did some archive digging and it was shorewall that got me on this. And then I went into conservative mode, as this impacted my firewall on Centos. Obviously overly conservative.

I am learning more, and this time, for example, I am trying hard NOT to edit http.conf, instead to put some http.d/00-init-nn.conf files together so I can know as much as possible what I have added. I don't know yet if that can be done. I have done this on my test mail server. Will see if I can do it on my web server.
