Subject: [PATCH] install: also configure ~/.zshenv
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The default login shell for users on macOS 10.15 changed from bash to
zsh.  So while generally nonstandard we need to configure it to make nix
function out of the box on macOS.

(cherry picked from commit 10202628b911980f05fc2c9460995af30f1bcbf3)
