On clean restart I cannot use 1Password git GPG SSH without manually logging into 1Password

On macOS there is a setting to automatically start 1Password in the background when logging in:

On Linux, that setting doesn't exist yet, so would currently require a manual additional as startup application/login item, e.g. using Startup Applications on Ubuntu, or systemd, depending on the Linux flavor.

We're looking into ways to improve this or at least better document it.
