I think what Tom=C3=A1=C5=A1 suggested above does not conflict with the des=
ign of
Nix and Guix.  As I understand it, he's suggesting that we have
'outputs' default to '("out" "debug") but then the debug outputs would
be immediately discarded for most packages.  This would save both disk
space and slave->hydra bandwidth.  Users could then get the debug
outputs by building the package locally.

I'm not necessarily advocating that we should do this, but wanted to
help facilitate communication.
