Guix on Windows?

[zimoun]

Dear Guixers,

We are not the 1rst April and I am not joking. :-)

Context:
 1. I am working in a lab in the middle of people using Windows for
processing biological data. And they will never switch to any Linux
flavor.
 2. I was previously doing research in electrical engineering labs
(applied maths) and a lot of people were using Mac.
 3. Echoing the Guix Days session about spreading the world
(dominating for the optimistic ;-))

(To escape ethical issues, the same arguments "why GNU Emacs is
running on Windows" apply here.)


Well, to extend a bit, let also include Mac and BSD.


I remember old discussion on guix-devel about Guix on MacOS. And if I
remember well, the issue is that there is "cheat" somewhere because
the GLibc. What is the current status?


Debian did a interesting "proof-of-concept" with kfreebsd [1],
replacing the linux kernel by the FreeBSD one. Do you think it is a
viable option for Guix?


About Windows, Nix propose some information [2] using the Windows
Subsystem for Linux (WSL) [3] to run on it natively [4]. Is it
affordable for Guix?


Last, if it is too difficult or technically impossible, then what is
the status of the cross-compilation targeting these systems?

Thank you in advance for any pointers and/or comment.


All the best,
