Hi,

Mathieu Othacehe <othacehe@gnu.org> skribis:

Unlikely.  Take
/gnu/store/qmzr030rzgikdxv3g9msqv0l8qp5j6y2-btrfs-raid-root-os.drv,
which was marked as failed earlier today due to missing .drv.  It’s a
4KiB file, and the cache-bypass-threshold is ‘guix publish’ is typically
set to something much higher than that.  So ‘guix publish’ won’t return
404 in that case.

If you find a “missing derivation” error in Cuirass, how would you
search logs to find what happened?  I’m not sure where to look for
useful debugging info.

Thanks,
Ludo’.
