Hi
I'm trying to build New Moon (unbranded palemoon browser) in parabola.The tmpfs i 2G which is way too little it seems.
I read the man page of guix-daemon and the manual and could not find away to point guix-daemon to another tmpdir than /tmp.
Is this a bug?
In case it is not possible to change on the guix side (before we rewritethe daemon) I think we should add a section about how to work around itto the manual.
-- Cheers Swedebugia

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,

Hi 😃
Thanks for the details. I agree that it is a bug.
I solved it by masking tmp.mount in systemd according to the arch wiki and thus disabled tmpfs for the whole thing.-- Sent from my k-9 mail for Android.

guix-daemon honors the TMPDIR environment variable, so you can run:
TMPDIR=/some/where/else guix-daemon …
See https://gnu.org/s/guix/manual/en/html_node/Invoking-guix_002ddaemon.html.
HTH!
