Tor Hedin Brønner d273db48c6 nixos/shells: avoid overriding the environment for child shells ... A shared exported guard `__NIXOS_SET_ENVIRONMENT_DONE` is introduced that can be used to prevent child shells from sourcing `system.build.setEnvironment` the second time. This fixes e.g. `nix run derivation` when run from e.g. ZSH through the console or ssh. Before this Bash would resource the common environment resetting the `PATH` environment variable. We also export `system.build.setEnvironment` to `/etc/set-environment` making it easy to reset the common environment with `. /etc/set-environment` when needed and to grep for environment variables in `/etc` (which was the motivation of #30418). This reverts changes made in b00a3fc6fd (the original #30418).		2018-08-30 13:20:39 +00:00
