It seems to be caused by the following line in the spec file's %postun: chkconfig --del ovirt-scheduler-proxy Post uninstall might not be a good place for it.. if the init file is managed by rpm, it was probably deleted already. Pavel, can you check if there are symlinks to the (probably missing) init file even after the removal in /etc/rc.*? If there are, we will have to change the section to %preun and try again. That will require a package rebuild, but no source code change (spec only).
