GNU Mes was created to address the security concerns that arise from
bootstrapping an operating system using binary blobs, which is common
practice for all software distributions. Mes is a Scheme interpreter
written in a simple subset of C and a C compiler written in Scheme and
comes with a small, bootstrappable C library. The Mes bootstrap has
halved the size of opaque, uninspectable binaries that were needed to
bootstrap GNU Guix, a functional GNU/Linux distribution that focusses on
user freedom, reproducibility and security. That reduction was achieved
by replacing GNU Binutils, GNU GCC and the GNU C Library with Mes. The
final goal is to help create a full source bootstrap for any interested
UNIX-like operating system. After three years of volunteer work funding
will enable us to make another big step forward and reach an important
new milestone.

@node Porting GNU Mes
@section Porting GNU Mes
Mes was written for x86-linux. A 64 bit (x86_64) is almost done, only a
few bugs remain. The Guix bootstrap for x86_64 uses x86 mes and that is
not expected to change.
An ARM (armv4/armv7l) linux port is underway. A port to GNU/Hurd
(x86-gnu) is also underway.
Initial scaffold, built by @file{build-aux/build-scaffold.sh}:
