description = ''
Extra environment variables to set when {command}`nix-darwin` invokes
{command}`brew bundle [install]` during system activation.
Useful for setting Homebrew's `HOMEBREW_NO_*` variables (e.g.,
`HOMEBREW_NO_ENV_HINTS`, `HOMEBREW_NO_ANALYTICS`, `HOMEBREW_NO_UPDATE_REPORT_NEW`)
that aren't inherited from the user's shell environment because activation runs
under sudo.
Each entry is prepended to the {command}`brew bundle` invocation in the form
`KEY=VALUE`, alongside `HOMEBREW_NO_AUTO_UPDATE=1` when applicable.
