bug#58309: [BUG Report] found a bug? followup

[Frank Pursel]

In hindsight, these errors occurred while my local network had a degradation that, no doubt, caused some file transfer interruptions.  I think this is to blame for these problems -- but -- I believe this may still point to opportunities to make guix file transfers more robust.  Interrupted file transfers should be detected and, queued for retry, and not result in store corruption or reports of store corruption.  Perhaps this problem occurs when incomplete file transfers are prematurely committed to the store?

Looks like a duplicate of the second part of
<https://issues.guix.gnu.org/58149#0>,
<https://issues.guix.gnu.org/53736#0> (*),
<https://issues.guix.gnu.org/53904>, <https://issues.guix.gnu.org/53974>
and <https://issues.guix.gnu.org/54708>.

(*) I think this one is interesting, as it seems to indicate that build
errors of packages aren't handled during "guix pull" -- there is a patch
available for that, though not applied yet IIRC.
