The logs in /tmp during installation

I have a machine that has Fedora Core 14 installed on it.  When I try to
upgrade to Fedora Core 15, I get a dialog that tells me I have "Dirty file
systems", and lists my Linux installation's root filesystem (i.e. /dev/sdb3) as
dirty.

It's not dirty.  It's fine.  I can boot it and all is well.

This bug has existed since at least FC 10.  See Bug 557989 for that story.

Comment 14 of Bug 557989 contains a method for working around it, involving a
rebuild of install.img .  I can't use that method now, since install.img is not
in /boot/upgrade, and I have no idea where it is now.

I'm more than happy to provide additional information, or run test scripts or
whatever, to identify the problem.  I've attached the logs that were in /tmp
during installation.

Here's my filesystem layout (from "df"):

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdb3            182821076  48591728 124788440  29% /
tmpfs                   512996       112    512884   1% /dev/shm
/dev/sdb1              1050640    119586    875718  13% /boot

P.S. I tried to post this as Bug 744953, but it got closed before I could even finish submitting the bug.  I mean, really.
