I tested libvirt-bin on quantal: the current archive version does not properly re-create /etc/dnsmasq.d/libvirt-bin symbolic link when installed, uninstalled, and re-installed.
The -proposed version does properly re-create the /etc/dnsmasq.d/libvirt-bin symbolic link.
(Ignore the verification-done -> -needed -> -done toggling; I mis-read my terminal's scrollback when transcribing details here.)
