Yes.
I've got it to work now. I've got a very minimal static kmod into the initrd and
that's now only loading modules for which supported hardware is present.
On the other hand, the initrd got 800 kiB larger - I'm not sure why modprobe
is so big... hmm...
Let's see the part Ludo adds to guix system init. Maybe we can also replace
modprobe by it - if we want.
