May be not, but socket activated services in systemd receive socket on stdin/stdout, not as argument. That's not entirely true. In inetd-style activation the sockets are passed as stdin/stdout. On systemd-style activation they are passed as sockets 3,4,5,..., i.e. the ones immediately following stdin/stderr/stdout. But anyway, the gist of it is true: socket activation requires proper support for it in the daemons. And just being able to set the socket path is not enough. Without patching zebra to support proper systemd-style socket activation (or even inetd-style as we support either) this is not available.
