I suppose this error message is accurate and the Where field is not
"/var/lib/xenstored"? What is it actually? What options did you pass
to ./configure when building Xen?

This seems like a silly misfeature of systemd to me, but I suppose the
fix is to rename the thing to match, except that would require all the
dependent units to have the field changed too. It might turn out to be
easier to instead arrange for @XEN_LIB_STORED@ to == /var/lib/xenstored.

@devs -- we obviously need to do something about this (too late for 4.5,
but for 4.6 + backport). Perhaps there is some alternative systemd
construction which disassociates the actual path from the abstract
service "xenstored dir mounted"?

Otherwise we'll have to somehow arrange for the file and everything
which depends on it to have a name which reflects the actual mount path,
which sounds pretty awful to me...

Ian.
