Well, TMPDIR= should Just Work :-)

You'll have to set it to the environment of guix-daemon (and 
restart the daemon) for it to have any effect.  How that's done 
depends on your service manager/init system.

I guess a ‘set-tmpdir’ RPC could be added to the protocol.  I 
haven't thought through the security implications, and IMO it's 
just papering over the real bug, which is…

Not sure what exactly you're referring to, but yes, I do think 
that using /tmp instead of /var/tmp (or any non-tmpfs) is a bug by 
modern(?) conventions.  It's guaranteed to break eventually on 
almost every non-Guix System, and when it doesn't it's an abuse of 
RAM and swap space.

Kind regards,
