How to Override the rpm.versions System

Overview

This document explains the files in the /var/cpanel/rpm.versions.d/ directory, which system administrators and third-party developers can use to modify cPanel-provided RPM management.

Files

The /usr/local/cpanel/etc/rpm.versions file contains cPanel-provided settings for the rpm.versions system, based on the version of cPanel & WHM that your server runs. However, the rpm.versions system allows any .versions files in the /var/cpanel/rpm.versions.d directory to override these settings.

The following table lists information about the files from which the rpm.versions system retrieves information:

Third-party conflicts

If a conflict exists between two or more third-party files in the /var/cpanel/rpm.versions.d/ directory, no RPM updates will take place.

A conflict can occur if two vendors modify the same setting in a file. You can resolve a conflict in either of the following ways:

1. If the /var/cpanel/rpm.versions.d/local.versions file contains a modification to the same setting that caused the conflict between the vendor files, the setting that the /var/cpanel/rpm.versions.d/local.versions file specifies will override the conflict.
2. The vendors can resolve the conflict through changes to their respective files in the /var/cpanel/rpm.versions.d/ directory.

File format

The files in the /var/cpanel/rpm.versions.d/ directory use the YAML format, and follow a structure that resembles the /usr/local/cpanel/etc/rpm.versions file. However, these files should only contain the values that you wish to specifically override in the rpm.versions system.

A file in the /var/cpanel/rpm.versions.d/ directory that overrides only one RPM target will appear similar to the following example:
