yum upgrade from F17 to F18

[Miroslav Suchý]

Hi,
I'm upgrading Fedoras by yum [1] for some time. I know that is not 
supported method and can have some problems. But the truth is that it 
was always less error prone as compared to upgrade using Anaconda or 
preupgrade. Even with upgrade from F16 to F17, which I originally 
thought would be impossible. But again "yum upgrade" was smoother than 
preupgrade.

As upgrading using yum require to have open wiki and follow steps 
written there, I decided to automate it and created script fedora-upgrade:

   https://github.com/xsuchy/fedora-upgrade

When run, it will upgrade your Fedora (currently only F17) to Fedora 18 
using "yum upgrade".
It is first shot, so it is definitely not intended for production 
systems. But you are very welcome to test it and report problems or just 
your ideas how to enhance it.
I intentionally left this script verbose, to help initial debugging.
