;) You described Gentoo! So I would suggest: "Install Gentoo". Try it,
you'll find that the "whims or habits of a distribution" in Gentoo
means flexibility and choices, and that appears what you're looking
for...

With stage1, you build your system "from scratch" including bootstrap,
in fact, having a stage3 rebuild will have the same effect, only that
you'll have a running system while you compile... Stage1 provides a
basic system, from what you'll start your own system.

What you need is simply portage, wich is the very heart of Gentoo, and
you also want some sort of package management, wich is portage. From
what you described, you want Gentoo...
