Nix develop shell not using custom TSL certificates

Hi!

I've ran into an issue with nix develop shells.

My setup:

• Nix Darwin (macos)
• Custom TLS certificates installed via nix darwin

Everything works as expected with the installed certificates, but as soon as I enter into a development shell with nix develop, the certificates are not available and thus, I get TLS errors that break whatever I'm doing in the dev shell. If I use an impure development shell, the issue disappears.

Is there a way to use pure nix develop shells which respect the installed certificates?
