Description of problem:

Upgrade of Fedora 11 to Fedora 12 failed with transaction error (file conflicts) on compiz libwall.so, wall.xml, compiz-wall.schemas, as well as kde.csh, kde-settings, kde.sh

System was onto CD 2 when error occurred, then hung on boot thereafter

Unable to run upgrade a second time as installer skips straight to new install & gives no option to upgrade existing system

Able to boot to single & running a yum clean & update now

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

Release 12 CD set


How reproducible:

Cant tell as no other system to destroy

Steps to Reproduce:
1. Run upgrade
2.
3.
  
Actual results:

As above

Expected results:

A clean upgrade

Additional info:

Will file a feature request as it seems odd (silly) that when an error like this occurs there are no other options in the error dialog box but to exit install/upgrade. Surely we need something the following options

1/ Submit Bug or save error message to a file
2/ Replace the conflicting files or skip & continue install/upgrade

Completely failing an upgrade which is 2/3rds done & not being able to recommence from where the error occurred or switch to another screen & remove the offending files as happened here is counter productive to say the least
