Yeah, this isn’t great.  Since 0.13.0 compilation is slower and requires
a whole lot more memory.  That’s a known problem.

There are some ideas to reduce the amount of compilation that has to
happen locally, but it isn’t quite as simple as a first look may

Could building be avoided entirely with substitutes? Are substitutes not appropriate for some reason, or is it just that substitutes are not produced on Hydra for every guix commit?

Thanks for clearing this up for a Guix beginner.
