+The next step that Guix has taken towards a Full Source Bootstrap is to
+replace the shell and all its utilities with implementations in Guile
+Scheme.  Gash (@pxref{Gash,,, gash, The Gash manual}) is a
+POSIX-compatible shell that replaces Bash, and it comes with Gash Utils
+which has minimalist replacements for Awk, the GNU Core Utilities, Grep,
+Gzip, Sed, and Tar.  The rest of the bootstrap binary seeds that were
+removed are now built from source by adding a new set of

+As Gash and Gash Utils mature, and GNU packages become more

+reduced again.

Great!  I wonder if we need a new section though.  Do you think we could
just keep it all in a single bootstrapping section that would describe
the current state of affairs, possibly with a “Bootstrapping History”
section or similar that would describe the milestones that got us there?

In fact, part of what you write here could very much go straight to such
a “History” section.  I think the terms “Full Source Bootstrap”,
“Scheme-Only Bootstrap”, etc. should only appear there, for clarity.

That way, the main bootstrapping section would simply describe the
current status in a standalone fashion.

Does that make sense?

I wouldn’t list them all here because (1) it’s hard to understand what
these names refer to, unless reading commencement.scm is your favorite
hobby ;-), and (2) it’s bound to become outdated.

WDYT?

It would be nice to have a couple of lines commenting the graph, like:

  The graph below shows the resulting dependency graph.  At its root
  there’s X and at the top there’s Y, etc.

Thank you, and apologies for suggesting more work!  :-)

Hello Ludo, Timothy!

Finally another version of the new bootstrap situation.  Timothy, please
have a look and feel free to change/add some things!

It's also getting time to write a blog post on this, would you like to
help out with that?

Thanks for your thoughts on this.  I started to rework this by adding a
History section but in the end I removed it again, describing the
current situation while mentioning the gcc-triplet reduction in Guix
v1.1.

Yes, instead of adding more of these, I also removed the previous list.

>> +As Gash and Gash Utils mature, and GNU packages become more

@Timothy: this is possibly touching very lightly on what Gash has
brought us; do you want to share some more here?

Of course, the old image should have been removed (Updated patch attached).

+Using these new binary seeds the ``missing'' Binutils, GCC, and the GNU
+C Library are built from source.  From here on the more traditional
+bootstrap process resumes.  This approach has reduced the bootstrap
+binaries in size to about 145MB in Guix v1.1.
+
+The next step that Guix has taken is to replace the shell and all its
+utilities with implementations in Guile Scheme, the @emph{Scheme-only
+bootstrap}.  Gash (@pxref{Gash,,, gash, The Gash manual}) is a
+POSIX-compatible shell that replaces Bash, and it comes with Gash Utils
+which has minimalist replacements for Awk, the GNU Core Utilities, Grep,
+Gzip, Sed, and Tar.  The rest of the bootstrap binary seeds that were
+removed are now built from source.
+
+Building the GNU System from source is currently only possibly by adding
+some historical GNU packages as intermediate steps <at> footnote{Packages
+such as @code{gcc-2.95.3}, @code{binutils-2.14}, @code{glibc-2.2.5},
+@code{gzip-1.2.4}, @code{tar-1.22}, and some others for details see
+@file{gnu/packages/commencement.scm}}.  As Gash and Gash Utils mature,
+and GNU packages become more bootstrappable again (e.g., new releases of
+GNU Sed will also ship in @code{tar.gz} format), this set of added
+packages can hopefully be reduced again.
+
+The graph below shows the resulting dependency graph for
+@code{gcc-core-mesboot0}, the bootstrap compiler used for the
+traditional bootstrap of the rest of the Guix System.
+
+@c ./pre-inst-env guix graph -e '(@@ (gnu packages commencement) gcc-core-mesboot0)' | sed -re 's,((bootstrap-mescc-tools|bootstrap-mes|guile-bootstrap).*shape =) box,\1 ellipse,' > doc/images/gcc-core-mesboot0-graph.dot

+
+The only significant binary bootstrap seeds that remain <at> footnote{
+Ignoring the 68KB @code{mescc-tools}; that will be removed later,
+together with @code{mes}.} are a Scheme intepreter and a Scheme
+compiler: GNU Mes and GNU Guile.
+
+This further reduction has brought down the size of the binary seed to
+about 60MB for @code{i686-linux} and @code{x86_64-linux}.
+
+Work is ongoing to remove all binary blobs from our free software
+bootstrap stack, working towards a Full Source Bootstrap.  Also ongoing
+is work to bring these bootstraps to the @code{arm-linux} and
+@code{aarch64-linux} architectures and to the Hurd.

@code{tar.gz} seems odd there.

Suggestion: @file{.tar.gz} if this is about the suggestion, or
``tar.gz'', or "as compressed tar files".

If none is satisfying, @samp{tar.gz} is still better than @code{tar.gz},
IMO.

Arguably, I would use @samp, not @code.

Ditto.

Better.

Added.

Ah, and now I see that it's too cryptic/terse too.  How about

and GNU packages become more bootstrappable again (e.g., new releases of
GNU Sed will also ship as gzipped tarballs again, as alternative to the
non-bootstrappable @code{xz}-compression), this set of added packages
can hopefully be reduced again.

Sure, 2x.

+Using these new binary seeds the ``missing'' Binutils, GCC, and the GNU
+C Library are built from source.  From here on the more traditional
+bootstrap process resumes.  This approach has reduced the bootstrap
+binaries in size to about 145MB in Guix v1.1.
+
+The next step that Guix has taken is to replace the shell and all its
+utilities with implementations in Guile Scheme, the @emph{Scheme-only
+bootstrap}.  Gash (@pxref{Gash,,, gash, The Gash manual}) is a
+POSIX-compatible shell that replaces Bash, and it comes with Gash Utils
+which has minimalist replacements for Awk, the GNU Core Utilities, Grep,
+Gzip, Sed, and Tar.  The rest of the bootstrap binary seeds that were
+removed are now built from source.
+
+Building the GNU System from source is currently only possibly by adding
+some historical GNU packages as intermediate steps <at> footnote{Packages
+such as @code{gcc-2.95.3}, @code{binutils-2.14}, @code{glibc-2.2.5},
+@code{gzip-1.2.4}, @code{tar-1.22}, and some others.  for details, see
+@file{gnu/packages/commencement.scm}.}.  As Gash and Gash Utils mature,
+and GNU packages become more bootstrappable again (e.g., new releases of
+GNU Sed will also ship as gzipped tarballs again, as alternative to the
+non-bootstrappable @code{xz}-compression), this set of added packages
+can hopefully be reduced again.
+
+The graph below shows the resulting dependency graph for
+@code{gcc-core-mesboot0}, the bootstrap compiler used for the
+traditional bootstrap of the rest of the Guix System.
+
+@c ./pre-inst-env guix graph -e '(@@ (gnu packages commencement) gcc-core-mesboot0)' | sed -re 's,((bootstrap-mescc-tools|bootstrap-mes|guile-bootstrap).*shape =) box,\1 ellipse,' > doc/images/gcc-core-mesboot0-graph.dot
+@image{images/gcc-core-mesboot0-graph,6in,,Dependency graph of gcc-core-mesboot0}
+
+The only significant binary bootstrap seeds that remain <at> footnote{
+Ignoring the 68KB @code{mescc-tools}; that will be removed later,
+together with @code{mes}.} are a Scheme intepreter and a Scheme
+compiler: GNU Mes and GNU Guile.
+
+This further reduction has brought down the size of the binary seed to
+about 60MB for @code{i686-linux} and @code{x86_64-linux}.
+
+Work is ongoing to remove all binary blobs from our free software
+bootstrap stack, working towards a Full Source Bootstrap.  Also ongoing
+is work to bring these bootstraps to the @code{arm-linux} and
+@code{aarch64-linux} architectures and to the Hurd.

I have to ask since we're talking about bootstrapability; is it actually
not bootstrappable or is it just harder/more complex? (The question is
more about the wording than about the logistics of it.)

OOC, why are you using single quotes here? You used double quotes
everywhere else. I assume this is an omission.

gzip is about 7000 LOC of simple C, can be compiled with tinycc (and
probably mescc), and we have gzip in Gash.  That Scheme code is not
trivial but with not too much work we can have Mes run that code.  It's
also conceivable to have an M2-Planet port of gzip.

xz is about 25,000 LOC of C and I only managed to build it after having
a full fledged gcc-4.6, gcc-2.95 or tinycc did not work for me.

So, if SED only ships xz-compressed tarballs, that makes
creating/maintaining the GNU bootstrap story more difficult.

Greetings,
Janneke

Yes, just an oversight.

+such as @code{gcc-2.95.3}, @code{binutils-2.14}, @code{glibc-2.2.5},
+@code{gzip-1.2.4}, @code{tar-1.22}, and some others.  For details, see
+@file{gnu/packages/commencement.scm}.}.  As Gash and Gash Utils mature,
+and GNU packages become more bootstrappable again (e.g., new releases of
+GNU Sed will also ship as gzipped tarballs again, as alternative to the
+non-bootstrappable @code{xz}-compression), this set of added packages
+can hopefully be reduced again.
+
+The graph below shows the resulting dependency graph for
+@code{gcc-core-mesboot0}, the bootstrap compiler used for the
+traditional bootstrap of the rest of the Guix System.
+
+@c ./pre-inst-env guix graph -e '(@@ (gnu packages commencement) gcc-core-mesboot0)' | sed -re 's,((bootstrap-mescc-tools|bootstrap-mes|guile-bootstrap).*shape =) box,\1 ellipse,' > doc/images/gcc-core-mesboot0-graph.dot
+@image{images/gcc-core-mesboot0-graph,6in,,Dependency graph of gcc-core-mesboot0}
+
+The only significant binary bootstrap seeds that remain <at> footnote{
+Ignoring the 68KB @code{mescc-tools}; that will be removed later,
+together with @code{mes}.} are a Scheme intepreter and a Scheme
+compiler: GNU Mes and GNU Guile.
+
+This further reduction has brought down the size of the binary seed to
+about 60MB for @code{i686-linux} and @code{x86_64-linux}.
+
+Work is ongoing to remove all binary blobs from our free software
+bootstrap stack, working towards a Full Source Bootstrap.  Also ongoing
+is work to bring these bootstraps to the @code{arm-linux} and
+@code{aarch64-linux} architectures and to the Hurd.
+
+If you are interested, join us on @samp{#bootstrappable} on the Freenode
+IRC network or discuss on @email{bug-mes@@gnu.org} or
+@email{gash-devel@@nongnu.org}.

Hi janneke,

Overall it is very good!  I only have a one small suggestion.

Honestly I think this says enough for now.  I have most of the code in
place so that Gash can build nearly anything.  (In particular, Awk is
nearly complete with respect to POSIX.)  It will take a while to clean
it up, but we can refresh this part when the new code lands.  :)

Is it too confusing to mention the Bash, Tar, and XZ binaries used to
get Guile up and running?  IIRC, there are a few packages whose sources
are still patched via “bootstrap-origin”, too.  I understand that those
binaries are really insignificant, but maybe someone new to this whole
thing would be surprised to discover “secret” bootstrap binaries.
Perhaps their role in unpacking Guile could be put in the footnote with
messcc-tools.  WDYT?

Good question -- I've added this

compiler: GNU Mes and GNU Guile <at> footnote{Not shown in this graph are the
static binaries for @file{bash}, @code{tar}, and @code{xz} that are used
to get Guile running.}.

Good question, changed it to "hard to bootstrap", like so

GNU Sed will also ship as gzipped tarballs again, as alternative to the
hard to bootstrap @code{xz}-compression), this set of added packages can
hopefully be reduced again.

Thanks for your input, pushed to master!
