You need to understand the implications of changing to the new style of booting before upgrading. After upgrading to the new style boot, your system will go to the boot method that RedHat used when it was installed. Also, any drop-ins you have enabled will be started at boot time. Edit Linuxconf's Addons and disable any daemons that will now be started with the SysV boot method.

This script will detect that, and clean up that install as well. Email me if you have any questions, or comments for a better script, or Linuxconf RPM in general.
