nightly fails due to missing disk space

[jdno]

We recently received a report in Zulip that the nightly release from 2023-10-22 was missing. The build failed with the following error:

thread '<unnamed>' panicked at src/smoke_test.rs:45:37:
called `Result::unwrap()` on an `Err` value: RecvError(())
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Error: No space left on device (os error 28)

A theory is that the temporary directory for the smoke test might need to be created on the attached disk to have more space, but this has not been confirmed yet.
