The file /etc/cron.daily/yum.cron is marked in the rpm as a 'config' file 
but perhaps should be config(noreplace) to avoid the need for such 
hackery with chattr...

ie currently the specfile contains:

%files
%defattr(-, root, root)
%dir %{_sysconfdir}/yum.d/
%config %{_sysconfdir}/cron.daily/yum.cron
%config(noreplace) %{_sysconfdir}/yum.d/yum.cron.excludes
%config %{_sysconfdir}/init.d/yum
%{_sysconfdir}/yum.d/

although chkconfig'ing it off (and making sure that the 
/var/lock/subsys/yum isn't present) is easy enough, ie currently the 
script contains a check:

#******************************
#Start the program
#But only if we're supposed to
#******************************
if [ -f /var/lock/subsys/yum ]; then
...

so running:

   chkconfig --level 2345 yum off
   service yum stop

should make sure that the yum.cron never active...
