I'm currently using tmpfs for /tmp, /run and /var/run on my Guix
Systems.

If you are interested, this is my base file systems:
--8<---------------cut here---------------start------------->8---
(cons* (file-system
         (device "none")
         (mount-point "/tmp")
         (type "tmpfs")
         (check? #f))

       (file-system
         (device "none")
         (mount-point "/run")
         (type "tmpfs")
         (needed-for-boot? #t)
         (check? #f))

       (file-system
         (device "none")
         (mount-point "/var/run")
         (type "tmpfs")
         (needed-for-boot? #t)
         (check? #f))

       (delete %debug-file-system
               %base-file-systems))
--8<---------------cut here---------------end--------------->8---

Thanks
