In Fedora 10 virt-manager.console gets installed in /etc/security/console.apps to provide consolehelper support. This file is user customizable but it's not marked as a config file in the spec file so it will get overwritten if virt-manager is updated:

%{_sysconfdir}/security/console.apps/%{name}

should be (i think):

%config(noreplace) %{_sysconfdir}/security/console.apps/%{name}

Also it would be nice if the virt-manager.console file could include ". config-util" at the top to allow it to include a shared config like other consolehelper config files (e.g. system-config-authentication).
