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 =E2=80=9CBootstrapping Histor= y=E2=80=9D section or similar that would describe the milestones that got us there?

I think the terms =E2=80=9CFull Sourc= e Bootstrap=E2=80=9D, =E2=80=9CScheme-Only Bootstrap=E2=80=9D, etc. should only appear there, for= clarity. That way, the main bootstrapping section would simply describe the current status in a standalone fashion.

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

(The question is > more about the wording than about the logistics of it.) 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.

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. :) > [...] > > +The only significant binary bootstrap seeds that remain@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. 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 =E2=80=9Cbootstrap-origin=E2=80=9D, too.

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@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.}.

(The question is > more about the wording than about the logistics of it.) 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.
