-Stage Anatomy
--------------
-
-The build of Raspbian is divided up into several stages for logical clarity
-and modularity. This causes some initial complexity, but it simplifies
-maintenance and allows for more easy customization.
-
- - **Stage 0** - bootstrap. The primary purpose of this stage is to create a
-   usable filesystem. This is accomplished largely through the use of
-   `debootstrap`, which creates a minimal filesystem suitable for use as a
-   base.tgz on Debian systems. This stage also configures apt settings and
-   installs `raspberrypi-bootloader` which is missed by debootstrap. The
-   minimal core is installed but not configured, and the system will not quite
-   boot yet.
-
- - **Stage 1** - truly minimal system. This stage makes the system bootable by
-   installing system files like `/etc/fstab`, configures the bootloader, makes
-   the network operable, and installs packages like raspi-config. At this
-   stage the system should boot to a local console from which you have the
-   means to perform basic tasks needed to configure and install the system.
-   This is as minimal as a system can possibly get, and its arguably not
-   really usable yet in a traditional sense yet. Still, if you want minimal,
-   this is minimal and the rest you could reasonably do yourself as sysadmin.
-
- - **Stage 2** - lite system. This stage produces the Raspbian-Lite image. It
-   installs some optimized memory functions, sets timezone and charmap
-   defaults, installs fake-hwclock and ntp, wifi and bluetooth support,
-   dphys-swapfile, and other basics for managing the hardware. It also
-   creates necessary groups and gives the pi user access to sudo and the
-   standard console hardware permission groups.
-
-   There are a few tools that may not make a whole lot of sense here for
-   development purposes on a minimal system such as basic python and lua
-   packages as well as the `build-essential` package. They are lumped right
-   in with more essential packages presently, though they need not be with
-   pi-gen. These are understandable for Raspbian's target audience, but if
-   you were looking for something between truly minimal and Raspbian-lite,
-   here's where you start trimming.
-
- - **Stage 3** - secure system. This stage configures SSH do disallow root
-   login, adds iptables rules, etc.
