It is currently not coded that way.

If the system was booted with systemd, and if staging is compiled with
--enable-systemd --prefix=/odd/path, and if I run
/odd/path/etc/init.d/xencommons start then xenstored will recognize that
systemd is running. But it does not recognize that xenstore was not
started by systemd itself. As a result socket activation will fail.

My idea to fix that case is to give xenstored a new --use-systemd-socket
and adjust the code accordingly.
