Bug 1187482

Description of problem:
File preservation not working, re-provision fails on 'initiate kickstart' step with error 'Error creating the new RAM disk'. Detailed output of 'rhn_check -vvv' contains root of the cause: initrd image, created by koan, is named as 'initrd.img_koan', but 'merge-rd.sh' is called with 'initrd.img' as a parameter, thus failing.

Version-Release number of selected component (if applicable):
server:
spacewalk-2.2
cobbler.noarch                   2.6.3-1.el6               @epel                
cobbler-epel.noarch              2.0.11-29.el6             @spacewalk

client:
koan.noarch             2.6.3-1.el6     @epel-centos6                           
spacewalk-koan.noarch   2.2.4-1.el6     @spacewalk-client-centos6 

How reproducible:
not sure. in my environment - 100% reproducible, however i dont have any other spacewalk installations to try on.

Steps to Reproduce:
1. create file preservation list
2. create/modify a kickstart, enabling file preservation list from step 1
3. re-provision some machine with a kickstart profile from step 2

Actual results:
re-provision fails on 'initiate kickstart' step with error 'Error creating the new RAM disk'. if machine nevertheless rebooted - kickstart starts with selected profile, however files included in 'file preservation list' are _not_ preserved.

Expected results:
successful kickstart with selected profile, all files from 'file preservation list' preserved.
