Update options clarification

Looking for a clarification on the various WHM update options. I've turned off automated OS updates, because they were regularly causing MariaDB to restart, resulting in dropped requests. Instead I plan to regularly move traffic to our backup server and update manually. Looking at the options in WHM, there are two: "update server software" and "system update". The documentation for these both point to the same page, which doesn't differentiate between them: Update Server Software - Version 82 Documentation - cPanel Documentation My guess is that "update server software" is what the automatic update calls, and presumably this updates everything cpanel is aware of. Presumably "system update" is a full yum update, which I'm guessing the automatic update doesn't normally do? Or does it do both? Or does one include the other? Or asked another way, if I turn off automatic OS updates, should I be running both "update server software" AND "system update" regularly? Or is "update server software" sufficient unless there's a reason to do otherwise?

  They both essentially do the same thing Update Server Software runs /scripts/rpmup
  which updates packages with the exception of the kernel System Update runs a full yum update
  including kernel updates (if you select it) If you want to run these updates manually you would need to set this at WHM>>Server Configuration>>Update Preferences -> Operating System Package Updates

  Thank you for the info. Can you elaborate on why there are two options that do the same thing? If the only difference between the two of them is that the system update has a checkbox to allow kernel updates, what is the purpose of the update server software option? IE what's the difference between calling /scripts/rpmup and running yum update?
