We either need to make XEN_LIB_STORED be hardcoded to /var/lib/xenstored
(i.e. ignoring localstatedir) or we need to make the systemd units
reflect the --localstatedir the user provided or we need to remove
--localstatedir as a user selectable option.

(the first is probably easiest, the second is probably more correct and
the third seems like overkill to me)

Xen doesn't include any sort of MUA, so that seems like hyperbole to me.

Not that I would recommend configuring Xen with localstatedir on /run
either mind.
