I was trying to install 7.1 beta.  I got through a little bit of the
package installation when it said it couldn't find an rpm file.  I noticed
that it was looking in /mnt/source/.....  instead of /mnt/cdrom/source/....
I don't know if that is an error or not, but it looks suspicious.  It kept
giving me the error, so I had to reboot.
	When I rebooted and tried to restart the upgrade (from 6.2), it would go
through the normal routine, asking me for keyboards and mice and such.
However, when I told it to build the list of packages to install, it
crashed.  Twice.  Once in graphical mode and once in text mode.  I only
managed to get the text crash on disk.
