$ ls $(guix build -e '(@@ (gnu packages commencement) libstdc++)')
include  lib  lib64  share

Aha! So I ran nix-garbage-collect (which deleted all the things),
rebuilt andd.... still the same :(

$ ls $(guix build -e '(@@ (gnu packages commencement) libstdc++)')
include  lib  lib64  share

What I would like as an end result is my host to be reproducible from a
`nixos-rebuild switch` command line, and then user's have access to
guix's wonderfulness. I'm realizing now also that if guix build's all of
it's own stuff anyways, then sharing the same daemon is just a win for
simplicity of runtime (only one daemon), but not much simplicity on disk
(still two profiles everywhere, almost an entirely separate graph on
disk).

So, I guess now I need to learn more about nix's configuration file to
get this set up in /gnu properly for users in a nixos way. An odd goal,
I admit.

Dankon por via helpo, Ludo!
