Fedora 17 Upgrade

So, to upgrade, rather than downloading a DVD image to a USB or disc and installing/upgrading from there, and instead of using the system updater (yum) to update OS versions like I do regular applications, I use pre-upgrade.  It purportedly offers you the complete experience that downloading an image does without any of the physical media woes.  Yay!



It has a few stages.  First, it downloads all the packages you'll need to your local machine for the upgrade (from Fedora 16 to 17 this time) and then it asks you to restart.  You then restart into a preupgrade mode which is a minimal system that runs an installer that updates your system.  It's great.



My first problem is this:

Key phrases being "An unhandled exception has occurred", "device has not been created", and "non-existent 0MB storage" with some UUID string.  I assure you, doctor, my devices exist and are relatively healthy.



It seems to be documented well by bug 823048.  I will try to fix that and then update you on my next problem. :)



UPDATE:

Bug 825500 ended up helping me resolve my bug.  There was an older root partition that wasn't being used that came first on my hard disk and Preupgrade was finding that instead of my active one.  Once I deleted that volume (using system-tool-lvm) Preupgrade + Anaconda proceeded perfectly smoothly. :)
