+	If you un-install libvirt and re-install it, you get a warning
+	from the post-install script:
+
+	  Installing     : libvirt
+	  ln: creating symbolic link `/etc/libvirt/qemu/networks/autostart/default.xml': File exists
+
+	See https://bugzilla.redhat.com/462011
+
+	* libvirt.spec.in: don't create networks/default.xml if it
+	already exists.
