Overall it seems ok, but needs some style cleanup, as noted below.

Unless theres the possibility of having read-only content, kup_server_content_t would be fine.

These should be grouped by type, so e.g. the two content lines should be grouped together

These can go up, grouped with the appropriate manage_*_pattern for the target type.
