# Motivations

- Philosophy/freedom. Sources-fist.
- Security. Refer to Reflections on Trusting Trust, by Ken Thompson.
- New architectures. Embedded distributions.
- Making sure that everything is built from Debian sources.

# Current efforts

## GNU Guix
Package manager, along with GUIXSD which is a non-Debian distribution. It is
reproducible and bootstrappable (cycle-free) from a seed roughly equivalent to
build-essential.

## GNU MES
Bootstrap roughly non-Debian build-essential from a simple C compiler.

## botch
Debian package metadata analysis.
https://bootstrap.debian.net/

Analyzes build-dep cycles; suggests how to cut cycles. Analyzes cross build
satisfiability issues. Analyses strongly connected components and their
evolution over time.

## rebootstrap
cross-bootstrap build-essential for one arch from a full binary seed of another.
https://wiki.debian.org/HelmutGrohne/rebootstrap

## nbs
Natively bootstraps a standard environment and toolchain starting from tcc and
musl.

## asmc
Natively bootstrap a Linux kernel from almost nothing. Binary blob of around 6kb
which contains a "G" compiler (simple, C-inspired, RPN, only int,
space-separated).
