Comment 8 for bug 1228210

Further discussion here: https://lists.ubuntu.com/archives/upstart-devel/2013-October/002772.html

Following that thread, I've come to the following conclusions:

libvirtd is perfectly acceptable in its current behaviour. upstart plans to support this edge case in the future. The only impact of this bug at the moment is in uvtool's postinst. A simple workaround can be used in uvtool's postinst. Although we can patch libvirtd to support "expect stop", it seems pretty invasive for something that we might want to drop in the future, and a the workaround in uvtool's postinst seems like the easier option.

So I'll mark this as Won't Fix in libvirt for now, to reflect the existence of this problem but my current intention to leave it as is. And I'll work around the problem in uvtool.
