Public bug reported: 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. $ sudo apt-get install libvirt-bin Reading package lists... Done Building dependency tree Reading state information...
