In a valiant effort at self help I read the line above and thought
... maybe I should add ...

(use-modules (gnu build file-systems))

... to the config (system41.scm)

Unfortunately this didn't fix things but it did produce an interesting
result: 'guix system reconfigure system41.scm' hung but added new
generation. Hey! guix is not supposed to do that. I want my money back!!

Interestingly, when I set --verbosity=5, 'guix system ...' failed and
refrained from adding a new generation.

So, no fix, but maybe a wormhole to plug ;-)

Log attached.
