FC2 -> FC5 Update (Anacoda Problem?)

[Steve McKelvey]

I am trying to upgrade from i386 FC2 to FC5 using CDs and the graphical 
version of the installer.  The mediacheck went fine.  The preliminary 
upgrade seemed to go fine through the checking dependencies stage.  Once 
that was done I hit "return" and got the message "Transferring install 
image to hard drive."  About two seconds later an error message popped 
up saying I was probably out of disk space.  Upon clicking on "Okay" to 
that message a second error message appeared mentioning an uncaught 
exception and suggesting it was probably an anacoda bug.  The anaconda 
log mentions something about a device being busy, presumably the hard drive.

 From running a df -h it seems I have plenty of disk space.

Filesystem            Size  Used Avail Use% Mounted on
/dev/hdc2              18G  6.9G  9.8G  42% /
/dev/hdc1              99M  8.2M   86M   9% /boot
none                  316M     0  316M   0% /dev/shm

Any suggestions on proceeding?  I know I can do a clean install of FC5, 
but would prefer to upgrade if possible.

Thanks for any help you can give.
