Description of problem:
When performing an kickstart upgrade from a CDROM the install crashses in the kickstart.py script. 




Version-Release number of selected component (if applicable):
anaconda-11.2.0.66-1

How reproducible:
Always


Steps to Reproduce:
1.Boot with this command

boot: linux ks=cdrom:/ks.cfg

2. Using the following ks.cfg file
--------------
upgrade
nfs --server=10.10.52.31 --dir=/export/fc7/ISO
lang en_US.UTF-8
keyboard us
network --device eth0 --bootproto dhcp
-----------------


Actual Results:
I get the following error

....
 File "/usr/lib/anaconda", line 949, in <module>
   kickstart.setSteps(anaconda)
 File "/usr/lib/anaconda/kickstart.py", line 1056, in setSteps
   upgrade.setSteps(anaconda)
AttributeError: 'bool' object has no attribute 'setSteps'
install exited abnormally [1/1]
....



Expected Results:
Should successfully upgrade!!

Additional info:
If I change the ks.cfg file to be an "install" instead of an "upgrade" with similar settings everything works fine.

Here's a snippet of the kickstart.py code line 949 is the problem.
-------------------------------------------------
945:    interactive = ksdata.interactive.interactive
946:    upgrade = ksdata.upgrade.upgrade
947:
948:    if upgrade:
949:        upgrade.setSteps(anaconda)
950:
951:        # we have no way to specify migrating yet
-----------------------------------------------------

It does appear that the upgrade variable is just a boolean, so I'm not sure how any upgrade would ever work????
