It's a good point, but I think "pretty much impossible" is an
exaggeration, because you can simply rename the failed build directory
from /tmp/guix-build-*.drv-0 to /tmp/guix-build-*.drv before debugging.

However, it's true that this would be a slightly annoying extra step
that is currently not required in the common case.

I don't feel strongly either way.  At first it seemed like a clear
improvement, but now I'm unsure.

     Thanks,
       Mark
