[systemd-devel] How do I make some environment variables available to user-mode unit?

[Andrei Dziahel]

Hey list,

I've create socket-activated user-mode unit[1] that sets up a SSH
tunnel, but it fails to start because ssh is unaware of ssh-agent
(gnome-keyring) because of empty environment. Is this possible to feed
ssh-agent-related environment variables to foo-tunnel.service making
gnome-keyring ask me to unlock openssh key?

Thank you in advance.
