This bug was fixed in the package lxc - 0.8.0~rc1-4ubuntu49
---------------
lxc (0.8.0~rc1-4ubuntu49) raring; urgency=low
* Don't directly write/remove /etc/dnsmasq.d/lxc as that's causing problems
when removing and reinstalling lxc.
Instead have dnsmasq ship /etc/dnsmasq.d-available/lxc and create/remove
a symlink in /etc/dnsmasq.d/. (LP: #1113821)

Bug description:
libvirt-bin deletes its own NON-obsolete conffile /etc/dnsmasq.d
/libvirt-bin in its postrm with "rm", but postrm runs on upgrade, so
this causes libvirt-bin to delete its own conffile on upgrade. Hence,
anything that relies on /etc/dnsmasq.d/libvirt-bin will break whenever
upgrading libvirt-bin to a newer version.
libvirt-bin probably should use dpkg-maintscript-helper rm_conffile.
Repro steps:
1) Install latest version of libvirt-bin. Observe that
/etc/dnsmasq.d/libvirt-bin is present.
2) Purge libvirt-bin and install an old version. Observe that
/etc/dnsmasq.d/libvirt-bin is present.
3) Upgrade libvirt-bit to latest version. Observe that
/etc/dnsmasq.d/libvirt-bin is gone.
Expected:
/etc/dnsmasq.d/libvirt-bin should be present on disk after each step,
since it is shipped in both versions of the package.
Actual:
/etc/dnsmasq.d/libvirt-bin is gone after step 3.
