Thanks Volker, Aron, and Ondrej. I think I understand most of Volker's
questions about HashDist  a lot better now.

One thing I wanted to clarify is that HashDist uses the abstract idea of
functional package management from Nix, but HashDist is not built on the
Nix package manager or a rewrite/refactorization of it. In particular, the
build recipes for packages are highly customizable and flexible.  We erred
on the side of pragmatism in several areas of the design due  to our
experience building complex  stacks on HPC platforms.

Another point I wanted  to underscore is that some of the functionality
like parallel builds across  packages and integrated, efficient development
workflows  have been part of the design since the early stages of HashDist
development.   There's just a limit to how fast we can implement features
because we all have primary research objectives  in other areas.  -Chris
