Hey Dan.

Can I suggest that instead of messing around trying to exclude only this patch, you go ahead and install the whole release and then change the messages, taking however long it takes. If any messages go out to managers between the time of the upgrade and the time that the message is changed then, at worst, the manager will get a message containing two copies of the information, contained inside a single email. If it was the other way around, that there was missing info during this period, then I would understand that you would definitely want to prevent it from happening (and we'd help to make sure it didn't), but if everyone is receiving all the information they need then I can't imagine how anyone could become upset.
