When you enable prelinking, you may experience problems with broken RPMs. See https://go.cpanel.net/how-to-disable-prelinking for further information =cut sub run { return 0 if prelink_is_wanted(); return 0 unless prelink_is_installed(); return 0 unless prelink_is_enabled(); # For more information, see CPANEL-4332. print "Prelink is installed and enabled.
