Comment 2 Brian Lane 2012-05-25 18:08:47 UTC 
Tried to do a preupgrade from F17 in a Parallels virt.
Comment 3 Brian Lane 2012-05-25 18:09:37 UTC 
Arrg. From F16. Fully updated before running preupgrade-cli.
Comment 4 Brian Lane 2012-06-02 17:56:26 UTC 
This is caused by parallels having an entry in fstab that starts with:

none /media/pfs prl_fs

A workaround would be to comment out or remove the line from fstab before upgrading.
Comment 5 Jon Burgess 2012-07-03 21:28:05 UTC 
I saw an identical traceback when doing a f16->f17 upgrade. In my case it was due to having a debugfs entry defined in /etc/fstab:

none    /sys/kernel/debug    debugfs defaults  0 0

I can give you the logs on a new BZ if they will help at all.
Comment 6 Brian Lane 2012-10-23 16:02:26 UTC 
Anaconda no longer handles upgrades.
