Christian Schneider updated SLING-8591:
---------------------------------------
    Description: 
The concrete case for this is that some customers would like to automatically 
install content packages that are deployed during a content distribution.

I would like to avoid putting the content package installation code directly 
into the content distribution core bundle. So the idea is to define a hook that 
can be implemented to support custom code after installation of a distribution 
package and before deletion of such a package.

The hook could look like this:
{code:java}
public interface PackageInstallHook {
    void onPostAdd(ResourceResolver resourceResolver, DistributionPackage 
distPackage);
    void onPreRemove(ResourceResolver resourceResolver, DistributionPackage 
distPackage);
}
{code}
The implementation of the hook can be offered as a service. A default noop 
service is created by default. The referenced service can be overridden by 
specifiying a installHook.target on the DistributionPackageBuilderFactory 
config.
