Bug 511929

Description of problem:

Using preupgrade to upgrade my fully-updated F10 system to F11, I get the following message during the preupgrade reboot:

"Upgrade root not found"
"The root for the previously installed system was not found."

I first tried this the week after F11 was released, and at least one each week since.  The observed behaviour is consistent.

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


How reproducible:

Every time!

Steps to Reproduce:
1. Run preupgrade as root
2. reboot
3. Observe anaconda messages
  
Actual results:

"Upgrade root not found"

Expected results:

Expect / to be found!

Additional info:

During my F9->F10 upgrade, done using yum, anaconda recommended I convert all my storage to LVM, so I did, and I have not touched the LVM configuration since.
