Hello Sergio,

> While I don’t have a specific starting point in mind, I believe that an essential feature such a tool, is the ability of continuing builds from successful phases.

While I haven't looked Nicholas' patches carefully, how do you think we could use Guix's build-system functionality as it stands now for a proper build system?

Olivier, have you thought about this? A sort of custom build-system (loke gnu-build-system) for each package to build?

Regards,
