[Xen-devel] [PATCH 5/7] tools/hotplug: systemd xenstored dependencies

[Olaf Hering <olaf@xxxxxxxxx>]

Everything which uses xenstored does this via the socket. Update the
existing service files to enable the xenstored.socket with the Requires=
statement. And schedule startup of the given service files after the
socket is enabled with the After= statement.
Once something tries to access the socket systemd will launch xenstored.
