How can I get it to affect nix-env too? What is the way to set this
globally, for all users? Namely, for my use-case, I'd like both root and
my own user to use this checkout.

Great. Is the package I push in then my responsibility in the future to
update?

It made getting the 32-bit proprietary blob much easier to try and get
working (which I have still not managed anyway). I'd welcome
instructions to run 32-bit software on 64-bit NixOS so that I could move
back to 64-bit. At the moment, 32-bit makes more sense to me.

Ah, OK, great!

No problem, I do not expect anyone to know or post the answer to all of
them.
