Motivation
there is a very confusing warning in the Nixpkgs manual that mischaracterises
nix-env
behavior, and this example shows what's really happening.Context
note that it doesn't use
pkgs.runCommand
or otherpkgs.stdenv
facilities, as deep down those setmeta.outputsToInstall
to very particular defaults that do not generally apply to Nix.Priorities
