Description
Stack's Nix integration, when enabled, implies `--system-ghc` but does not imply `--no-install-ghc`.
In principle, a user-supplied `shell.nix` file might not put the needed (specified) GHC version on the path in the Nix environment without the `nix-shell` command failing. With `--install-ghc`, Stack will go on to try to install the specified GHC version.
Elsewhere, @chreekat has reported that he has experienced this.
Is `--install-ghc` a sensible default, when Stack's Nix integration is specified?
