Oh thanks! :-)

Well, from my understanding, Guix (package manager) and Guix System
(OS on the top) are not about bootstrap.  If you give a look at one of
the first public presentations:

<https://people.bordeaux.inria.fr/lcourtes/doc/guix-ghm-2012.20120721.pdf>

then bootstrap the whole toolchain was not on topic (at least not
explicitly listed).  Reducing the bootstrap seed came later and
gradually, for instance see:

<https://archive.fosdem.org/2017/schedule/event/guixsdbootstrap/>
<https://archive.fosdem.org/2019/schedule/event/gnumes/>

I have read the White Paper and the doc.  I am sorry but I miss which
problem Xiden is solving and how it does.  For instance, I do not
understand what a "launcher" is and what its job is.  Maybe Xiden is a
"workflow" engine?

The bootstrap path of Racket in Guix is not clear to me.  I miss if a
Racket interpreter or compiler in its binary format is used (as
Haskell for instance) or if all is compiled from source using tools
already bootstrapped.  Anyway, I miss what you would like bootstrap?
If you mean a trusted seed in order to start a package collection, you
could use the current Guix binaires---as a starting point.

Well, from my understanding, as Philip said, compile Guile to Racket
linklets seems something promising. :-)
