I'm a bit wary about GuixSD packages declaring being able to write to
/var/ anything by default.  What would the permissions be?  I guess if
it were world-writable to all "users" group users it would be okayish.

Note that KoboDeluxe includes a patch snarfed from Debian that comments
out the ability to save score files for this same reason, and it was
marked in Debian as a security patch IIRC...
