I'd like to change my Guix System to build packages in a different location (`/dev/shm/`) so that they are built on a tmpfs partition to hopefully speed up builds (defaults to `/tmp` which is on the `/` partition on Guix System). The Guix Manual only mentions that this may be done by setting the environment variable `TMPDIR`.
I was able to do this for a system that is configured as a foreign install by modifying the SystemD service file (Guix Mailing List), but I haven't been able to figure out how to modify my `/etc/config.scm` file to do this on Guix System.
Not just this, most (?all?) browsers now support viewing standard PDF documents… So, they shouldn’t even need to installing anything as long as they aren’t using IE…
