bug#71214: bordeaux linux-libre-6.8.10-guix.tar.gz corrupt nar

[Richard Sent]

Hi Guix!

The nar for
/gnu/store/y813phs2n9xnb7zbcr07g0j9509bzbsb-linux-libre-6.8.10-guix.tar.xz
on Bordeaux seems to have been corrupted by some mechanism. The URL in
question is

> URL: nar/none/y813phs2n9xnb7zbcr07g0j9509bzbsb-linux-libre-6.8.10-guix.tar.xz

>From comments by cbaines on an earlier issue [1] that had misdiagnosed
the problem:

For reference:

On a related note, whatever issue is going on here seems to cause [2].
The actual issues are distinct.
