My thoughts exactly, and very nice to hear you say it too!

Sure!

Re-confirming this now, "already" up to...

    building /gnu/store/1kj9y2qkd7nc7jhyfa0ywqkbmbv4a8ki-gcc-mesboot-4.9.4.drv...

Ah that's a nice trick.  No changes!

    $ ./pre-inst-env guix build coreutils -s powerpc64le-linux -d
    /gnu/store/rsg7k7rih8giz2a3gbd281ygzixzg5yn-coreutils-8.32.drv

OK.  I have reset wip-full-source-bootstrap and will send a v3 patch
series.  We probably want to think about/change the actual mirror spell
"mirror://gnu/guix/mirror/" (?) to use (see other mails).

Done.

Yeah, what a bonus.  The thing is that stage0-posix includes mescc-tools
and m2-planet; we were expecting at least two extra packages...

Thats really great to hear, it means a lot to me.  I'm very grateful for
all your support in this journey and for Guix, that presented me with a
beautiful piece of code to play with and prototype the bootstraps.  And
also, many thanks for the opportunity to stepwise introduce these
changes.  Time to start thinking about the next big step for
bootstrappable!

Greetings,
Janneke
