Overview

This package provides a universal hook plugin for yum based systems (e.g. CentOS 7) and dnf based systems (e.g. CentOS 8).

This plugin allows us to run scripts at various entry points in the yum or dnf process.

If you install scripts for this plugin to run you must install them in the correct locations on yum systems and the correct locations on dnf systems. The details are documented in each system’s Plugin Documentation below.

• Design Doc
• DNF Plugin Documentation
• YUM Plugin Documentation
• APT Plugin Documentation

Note: On dnf based systems it requires Python 3.6 and also Provides: dnf-plugin-universal-hooks.

Testing

Note:

• install-zsh-test-hooks.sh will create some dummy hook scripts for zsh RPM.
• on dnf systems you can use the dnf command instead of yum if you like
• on apt systems you must use apt instead of yum

1. yum install yum-plugin-universal-hooks
2. cd into repo
3. ./install-test-zsh-hooks.sh
4. Do a transaction involving zsh
   • e.g. if you already have zsh: yum reinstall -y zsh
   • e.g. if you do not already have zsh: yum install -y zsh
5. Note the output shows that they were executed properly. For example, on a dnf machine it will look like this:
