Description of problem:
I am trying to upgrade from 12 to 13 using preupgrade. After I reboot and the software install part (I assume) begins, the python codes chokes on what appears to be the fact that I chose to use a configuration where KEYTABLE=emacs instead of default (and presumably heavily tested) "us" (this is of course, because the "emacs" layout puts the control key where God *himself* intended it -- no really, it's in one of the later epistles...I swear). I have now seen this happen at least 3 separate times. In this latest attempt, once I was rebooted back into F12, I reverted /etc/sysconfig/keboard and tried the preupgrade process again, but I think the old keyboard layout information got cached somewhere because the upgrade choked in the exact same way (with the same python traceback) and I know that the *only* file I changed to get the emacs layout was /etc/sysconfig/keyboard. I did try to save the bug information and the tool claimed that it was saved -- and *apparently* somewhere in /root, but I have not been able to locate it :-( Sorry about that. 

I should also mention that my /boot was too small to handle whatever it was the preupgrade wanted to throw in there, so I got that warning dialog, but since I this was a wired machine, I was able to simply defer the operation until after the reboot. 

Version-Release number of selected component (if applicable):
preupgrade-1.1.8-1.fc12.1.noarch

How reproducible:
Very. It has happened to every attempt I've made to upgrade from 12 to 13 and I believe also on one attempt to upgrade 10 to 11 (I do run a boatload of fedora machines here at home)

Steps to Reproduce:
1. Load F12 on a wired machine with a small /boot that won't allow preupgrade to do whatever it is that having a small /boot won't allow preupgrade to do.
2. Update /etc/syconfig/keyboard so that KEYTABLE="emacs"
3. Yum up to the latest (I dunno if this is strictly necessary)
4. Run preupgrade and follow the instructions. 
5. At some point, after the reboot, while trying to load /install.img, the error should appear. 
  
Additional info:
I realize that this is not a high priority ticket since only idiots like me muck with /etc/sysconfig/keyboard, but I put the severity at "Urgent" because for those poor sods who *do* tickle this bug, on-line upgrades are an impossibility (well -- that may not be true. I have not tried reverting /etc/sysconfig/keyboard before running preupgrade for the first time -- I image that would avoid the problem).
