Hey, I have FreeBSD 9.0-STABLE and I'd like to update straight to 9.1-STABLE. However, whenever I run build/make world, etc, then I end up with 9.1-RELEASE and have to run another build/makeworld to get 9.1-STABLE (or, in recent days, 9.1-PRERELEASE). It'd be nice if I could just go straight from 9.0-STABLE to 9.1-STABLE. Does anyone know how to do this?
