Thanks for the input Jerry.  Lot's of good ideas on how to manually work
around the issue.  The preupgrade target user is typically one who might
not be fully comfortable with some of the manual workarounds on the
table.  Ideally, a preupgrade maintainer will be addressing a method to
make this process more smooth for Fedora 13, but for now we're looking
to avoid leaving the average user high-and-dry, and documenting
suggested workarounds (as you've noted above) in the Common_F12_Bugs
page.

Thanks,
James
