Hi,

ilmu <ilmu@rishi.is> skribis:

> Early cutoff is a very desirable property that nix does not have (and I assume therefore that neither does guix).

The “intensional model” that Julien mentioned, or what the Nix folks now
refer to as “content-addressed derivations”, have this early cutoff
property.  It’s one of the main motivations for this whole endeavors.

This document shows how Nix folks are working on retrofitting
“content-addressed derivations” into Nix:

Thanks,
