Description of problem:
While doing an upgrade from 6.2 to 7.1 using a network boot disk and
installing from an NFS mounted CD-ROM drive, the upgrade got through
about 3/4's of the upgrade and then produced this error message:
"The file /mnt/source/./RedHat/RPMS/emacs-20.7-34.i386.rpm cannot be
opened.  This is due to a missing file, a bad package, or bad media.  Press
<return> to try again."  Pressing the "ok" button (which is the
only option) brings up the same error message repeatedly.  Looking on the
RedHat CD's I see that the file in question is -not- on CD1 but is
instead located on CD2.  I tried unmounting the CD to put in the other
disk but I can't unmount (drive busy, even if I try forcing it) and
since the disk is spinning, the manual override for opening the tray
door is disabled.  Thus there's no way to change the CD and the
program is stuck in a loop.  I tried changing consoles to the
shell prompt and pressed return and it doesn't respond at all.
It appears to me that some rpm's were placed on the second CD
but the installer has no provisions for volume changes.  A work
around is probably to copy the CD's to disk.

How reproducible:
Didn't try yet

Steps to Reproduce:
1. Get hold of a RH6.2 system with emacs installed.
2. Start a network upgrade to 7.1 using an NFS mounted CD.
3. When the installer goes looking for emacs, see what happens.
	

Actual Results:  Installation is caught in a loop because it can't find the
file
because the file isn't there and there's no way to direct it to
where the file is (on the other CD).

Expected Results:  Instead of just presenting an "ok" button, entering a
path to
the file or allowing the remote CD drive to be temporarily unmounted
would be helpful.
