Good info: How to automatically apply a client Hotfix as part of a client push or client installation
This blog post has been deleted at request of Microsoft due to issues. From Microsoft:
"Several of us at Microsoft were recently blogging / writing about the use of the ClientPatch folder in Configuration Manager. As it turns out, this feature wasn’t actually supported and can could cause some issues. The KB reference and corresponding blog entry on the supportability blog have been removed. We have a new blog entry coming online in the next day or two to clarify the situation. "
