At least on Archlinux, /tmp is a tempfs and hence in RAM, and limited in size to half the available memory. Solaris and Fedora also do this apparently.

For me to use SigStore I'd like to provide a custom directory for the temporary files.

iirc it can be customized with the TMPDIR env var

oh right; that may be sufficient indeed. Would be good to document this.

yeah its in std::env::tmp_dir but I forget every time

Yes, I think of doing it every time and then I forget. It might be useful to have a settable temp dir tho.
