I was wondering if it's commendable to mount /tmp as tmpfs with GuixSD.
I think it could be useful to speed up Guix builds.

What would be the best way to do so?
Can't test now, but what about

     (file-system
       (mount-point "/tmp")
       (device "tmpfs")
       (type "tmpfs")
       (flags '(no-dev no-suid))

?
