Toggling a more verbose build process rather than bare black-box

As far as I have observed so far in my (very novice) experience with NixOS, when running $ sudo nixos-rebuild switch, sometimes there is progressive output informing me about what the package manager is doing, but it is usually fairly sparse and non-specific. It’s mostly just a black box when I compare it to my experience with other Linux distros such as pacman or portage.

How do I tell NixOS to be more explicit about what state the package manager is in whether it is:

  1. downloading packages,
  2. installing packages, and/or
  3. building packages from source?

You can wrap your nixos-rebuild with nom: GitHub - maralorn/nix-output-monitor: Pipe your nix-build output through the nix-output-monitor a.k.a nom to get additional information while building.

This GitHub project as described in the readme sounds wonderful! If it runs as described, then it should come by default in Nix.
