It would mean giving up some control over exactly what composes the
image (or fighting doubly hard to get it back), but check out jigdo-file
and using it to generate debian testing/unstable images.

I think you can also use jigdo for other distros including a
roll-your-own, but I don't know anything about doing that.

right keys at the right time and the instrument plays itself.
