Mount /tmp as tmpfs?

Mount /tmp as tmpfs?

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))

?

I use:

(file-system
  (mount-point "/tmp")
  (device "none")
  (title 'device)
  (type "tmpfs")
  (check? #f))

And it works perfectly.

Guix maybe, for a developer system you run out of RAM for everything
that has serious demands in RAM and/or Diskspace for building.

If waste of writes is your concern, getting a separate disk for
/tmp is a good choice. As long as you don't have to build big
applications from source/without substitutes tmpfs is alright.

Been there, tried that and considered it now only for machines that
will never build anything big.

Well yes, my tmpfs works perfectly, but I forgot to say that I have 128G
RAM.

For the record, I used to compile Gentoo packages in a tmpfs
on a machine with 8GB+ RAM.  Beside qtwebengine (which would work with
a 5GB tmpfs), I never had an issue.
