Guide to Standardized Hooks - RPM::Versions Functions
The RPM::Versions category creates hookable events for RPMs. cPanel & WHM ships with the preconfigured RPM::Versions hooks.
The /var/cpanel/legacy_hooks touch file determines whether the system has already created the following hooks. To prevent the creation of these preconfigured hooks, touch the file before you install cPanel & WHM.
RPM
RPM::Versions events use the RPM naming format, where RPM is the name of the RPM to associate with the hook.
Information
- Action code runs as: The WHM user.
- Blocking attribute: Available.
- Escalate privileges attribute: Available.
Available stages
-
pre— Hook action code runs before the event. -
post— Hook actions code runs after the event.
Returns
The pre and post stages do not produce output.
