Well, you said you thought you knew the answer, so I can confirm you know it. However what I'd like to be able to do soon is to feed patterns from the CLI, which would be much better than doing so from a reload since it would work inside a chroot and would allow one to perform partial replacements.
It's not necessarily difficult to implement, it just requires some time and some care. If someone is interested in doing it soon, I can give a few hints on that.
