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.

Subject: GNU Mes 0.20 released
<#secure method=pgpmime mode=sign>
We are pleased to announce the release of GNU Mes 0.20, representing
147 commits over 38 weeks.
Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap
a GNU/Linux system without binary GNU toolchain or equivalent).
This release is a step towards the upcoming Scheme-only bootstrap and
bringing Mes into NixOS and Debian. This effort is now sponsored by
NLnet[12].
Next targets:
- ARM support
- Reduced Binary Seed bootstrap for ARM
- Scheme-only bootstrap: use Guile and Gash to remove bash,
coreutils&co, grep, sed, etc. from the Guix bootstrap binaries
- mes-m2: port Mes.c to M2-Planet
- Introduce Reduced Binaries Seed bootstrap to NixOS
- Debian?
- Hurd
Packages are available in Guix master.
* About
GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to GNU Guix[2]
and potentially to any other interested GNU/Linux distribution, and
aims to help create a full source bootstrap as part of the
bootstrappable builds[3] effort.
It consists of a mutual self-hosting Scheme interpreter written in
~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme.
This mes.c is being simplified[4] to be transpiled by M2-Planet[5].
The Scheme interpreter (mes.c) has a Garbage Collector, a library of
loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS
[portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8] --and test
suite just barely enough to support a simple REPL and simple
C-compiler: MesCC.
Mes+MesCC can compile an only lightly patched TinyCC[9] that is
self-hosting. Using this tcc and the Mes C library we now have a
Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5,
binutils-2.20.1, gcc-2.95.3. This is enough to bootstrap Guix for
i686-linux and x86_64-linux.
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10] -- John
McCarthy page 13, GNU Guix's source/binary packaging transparency and
Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler.
* Download
git clone git://git.savannah.gnu.org/mes.git
Here are the compressed sources and a GPG detached signature[*]:
https://ftp.gnu.org/gnu/mes/mes-0.20.tar.gz

Use a mirror for higher download bandwidth:
https://ftpmirror.gnu.org/mes/mes-0.20.tar.gz
https://ftpmirror.gnu.org/mes/mes-0.20.tar.gz.sig
Here are the MD5 and SHA1 checksums:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx mes-0.20.tar.gz
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx mes-0.20.tar.gz
[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify mes-0.20.tar.gz.sig
If that command fails because you don't have the required public key,
then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273
and rerun the 'gpg --verify' command.

@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.
