[arch-general] Env variable of user unit of ssh-agent not set

[Rainer Dorsch]

Hi,

I followed

https://wiki.archlinux.org/title/SSH_keys#Start_ssh-agent_with_systemd_user

It seems that SSH_AUTH_SOCK does not get set although it is in the user unit 
file.

$ systemctl --user status ssh-agent.service

Can anybody tell what I am missing?

Any hint or advice is welcome.

Thanks
