Hi Guix!

It seems that build logs are not copied over from build nodes, 
leading to amusing (but alas quite useless) output like:

~ λ curl $(guix build zstd --log-file)

bug#55985: Cuirass(?) produces less than useful ‘build’ log files

What you have here *is* the log as Cuirass saw it, but…

It turns out zstd, in this case, was already built on the node it got it
from, so the log just shows that.

I admit this is suboptimal.  From the perspective of Cuirass though, it
looks like “business as usual”, and it cannot really be distinguished
from a situation where the thing actually got built.
