Guix should correctly report that it ran out of space instead of falsely
mentioning hash mismatches and attempting alternative download sources,
as demonstrated by the Guix output below:

Could you post the log returned by ‘guix build --log-file
/gnu/store/dqzq8hbk8gqx5lhmnxsl5vl0c6s3i0a2-tcpdump-4.9.3.tar.gz.drv’?

The root cause is that ‘false-if-exception*’ as used in (guix build
download) is too coarse-grain.

Thanks,
Ludo’.

Ah, I hadn't thought about that the same derivation would be produced
(same hash) upon retrying.  I had of course retried after running 'guix
gc -F5GiB'.  I'm afraid I've lost that log.  The next time the problem
occurs I'll make sure to preserve it.
