Hi,
I realize that my question is a bit far from flox, but this is still a result of not using brew nor NixOS.
I was able to install the [`yubikey-agent`](https://github.com/FiloSottile/yubikey-agent) package to give access to my new yubikey. However I can’t find how to start the downloaded executable as a service with `launchctl` on Mac. Is it something that someone already attempted? If not, don’t worry, I’ll keep on digging.
Thanks.

Did you ever figure out how to do this? I haven’t attempted to do it, but I’m guessing you could start `/Users/matthew/.local/share/flox/environments/mkenigs/aarch64-darwin.default/bin/yubikey-agent` with `launchctl`.
This does start to touch on user-wide configuration, which flox hasn’t addressed yet. I’m curious, would you want something like starting yubikey-agent to be part of your default environment? You could add that in `shell.hook` of your default environment, but I’m not sure that’s the right place for it. And maybe you can only have one instance of yubikey-agent? There’s probably some things that should be part of system or user config that flox doesn’t support yet. Maybe we should integrate with [GitHub - LnL7/nix-darwin: nix modules for darwin](https://github.com/LnL7/nix-darwin)

Hi Matthew,
> I’m curious, would you want something like starting yubikey-agent to be part of your default environment?
Yes that’s certainly the kind of thing I would like to do in that case.
> And maybe you can only have one instance of yubikey-agent?
Indeed.
Coming from Homebrew I would probably have done [`brew start`](https://github.com/FiloSottile/yubikey-agent#macos) in the past, but I didn’t know what would be the right approach with flox.
