I had a minimal F8 vmware VM, and yesterday intended to do a yum upgrade 
to get to rawhide. I installed fedora-release which gets me the 
fedora-development.repo and fedora-release files.
I then tried a yum check-update, and saw the heap of updates.
Next I yum update rpm* yum*, which seemed OK.
After that yum didn't work anymore.
rpm was still working, so I upgraded groups of packages at a time.

I managed to kill it in this process by running out of disk space while 
  upgrading glibc, and others ;( and now she doesn't run commands or 
boot, I'm going to try again to get the error message.
