Is it somehow possible to use composed ENV vars in a systemd unit file?

Simple example, env file has

ADDRESS=foo
PORT=bar
LISTEN=${ADDRESS}:${PORT}

putting ${ADDRESS}:${PORT} directly in the unit file works, $LISTEN not.

Does systemd supports such var substitution?


Answering my self :-)

No, "Variable expansion is not performed inside the strings" see

man systemd.exec
