FWIW I have code that I was planning to polish and submit (hopefully
next week) that determines modules needed for a particular device by
walking /sys.  In addition, I thought we could make the initrd module
list a first class field of ‘operating-system’.  With these two pieces,
‘guix system’ should be able to warn when a module is missing.
