Hi Prasad,

The is a for loop that checks for "debug kdump PAE xen" variants in the script 
and adjusts the name accordingly. It should catch the cases you are talking 
about. Let me know if it doesn't.

I have also updated the script so it only prints out the needed packages when 
run by a normal user (normal user can't do rpm install so why even try?). When 
run by root it will attempt to download the packages and install them.

I have attached the revised version of the script to this email. The script is 
also checked into the git repository in the documentation section:
