Description of problem:
We see following warning message while kickstarting RHEL 6 machine from satellite v 5.4 : 

WARNING /usr/lib/python2.6/site-packages/pykickstart/parser.py:733: DeprecationWarning: Script does not end with %end.  This syntax has been deprecated.  It may be removed from future releases, which will result in a fatal error from kickstart.  Please modify your kickstart file to use this updated syntax.#012  warnings.warn(_("%s does not end with %%end.  This syntax has been deprecated.  It may be removed from future releases, which will result in a fatal error from kickstart.  Please modify your kickstart file to use this updated syntax.") % _("Script"), DeprecationWarning)

Version-Release number of selected component (if applicable):
Red Hat Network Satellite v 5.4 

How reproducible:
Always

Steps to Reproduce:
1. Create RHEL 6 kickstart profile on satellite v 5.4 
2. Try to install a system via same kickstart 
3. Check the anaconda.log 


Actual results:
The anaconda log shows following warning messages :
WARNING /usr/lib/python2.6/site-packages/pykickstart/parser.py:733: DeprecationWarning: Script does not end with %end.  This syntax has been deprecated.  It may be removed from future releases, which will result in a fatal error from kickstart.  Please modify your kickstart file to use this updated syntax.#012  warnings.warn(_("%s does not end with %%end.  This syntax has been deprecated.  It may be removed from future releases, which will result in a fatal error from kickstart.  Please modify your kickstart file to use this updated syntax.") % _("Script"), DeprecationWarning)
INFO    Running kickstart %%pre script(s)

Expected results: 
There should not be an warning messages thrown by anaconda. 

Additional info: 
Anaconda in RHEL 6 expect %end for every  %pre and %post script section. When satellite v 5.4 creates kickstart for RHEL 6 then the %end is not added for any of the %pre and %post section. It seems this is causing the warning message. 

I downloaded the kickstart created by satellite and added %end manually then kickstarted the RHEL 6 machine and this time there was no such warning message related to %end.
