You can order them using user targets.
Ie, create a ssh-agent.target and have the default target depend on it.
Now your ssh-agent is guaranteed to be online when the default target comes up.

But, since the unit is already setting a fixed path for the agent, I would just put that path in my .profile and call it a day. Having systems do environment variable injection seems too fragile to me, especially for static variables.
But yeah, `environment.d` or `.profile` would be simpler. I mostly opted to keep everything in one place.
