Bug 630666

Description of problem:
Cannot kickstart a system on Spacewalk 1.1

Version-Release number of selected component (if applicable): 
1.1

How reproducible:
Every time 

Steps to Reproduce:
1. Create a new kickstart
2. View the kickstart and verify the %post line before the GPG imports has %post --logfile /mnt/sysimage/root/ks-rhn-post.log in place automatically put by spacewalk.
3. Try to kickstart a system. 
  
Actual results:
Kickstart fails with:
Traceback (most recent call first):

chroot: <function chroot at 0xdc43f50>
command: /bin/sh
stderr: /mnt/sysimage//mnt/sysimage/root/ks-rhn-post.log
root: /mnt/sysimage

If the kickstart in /var/lib/rhn/kickstarts is manually edited to read %post --logfile /root/ks-rhn-post.log (ie remove /mnt/sysimage) teh kickstart completes okay.


Expected results:
Kickstart shoudl complete okay with an installed system.

Additional info:
This spacewalk server has been incrementally updated over the past year or so from 0.8 through to 1.1 as each version has come out. This is the first time I have tried to kickstart on 1.1.
