Sorry, I meant to preserve #:container? behavior but I forgot this bit.

I believe the attached patch provides an Even Greater Way to address the
problem, namely by making the modprobe/firmware thing an optional
service.

Could you try and report back?  I tried it in a VM and there’s no
regression.

Besides, we’ll have to make sure ‘guix system extension-graph’ honors
--container.
