Embed update handler into bundles for handling content updates
---------------------------------------------------------------
Key: SLING-388
URL: https://issues.apache.org/jira/browse/SLING-388
Project: Sling
Issue Type: New Feature
Components: Core
Reporter: Alexander Saar
As discussed on the list [1] the provision of initial content contained in
bundles leads to the question how to handle content updates contained in new
versions of bundles. While a simple overwrite flag may be enough for
development, there might be more complex cases where you have to consider the
(maybe modified) content in detail - or want to change the content for the new
bundle version - if you update bundles on several production installations. For
that purposes it would be nice if one could embed the update procedure directly
into the new (updated) bundle and tell Sling which one shuld be used by adding
an according bundle header parameter.
