Thanks!
I have already did with singularsyntax/guix-bootstrap-alpine but then
I hit some issues... Well another story. :-)
Why there is (in both images) 13 "layers"?

But "docker pull" downloaded 13 layers, well because these numbers are
closed, is it meaningful? Really naive question.
Other said, is it not something from the Docker side?
Well, it is like Guix deletes something but this something is empty
(from the Guix side):

abd the "real" target is still something on the filesytem side (du -sh).
Bah, I am not enough familiar with Docker...
Good night,
