The current fstab is:
/dev/sda8       /                       ext3    defaults        1 1
/dev/sda1       /boot                   ext3    defaults        1 2
/dev/sda7       /usr/local              ext3    defaults        1 2
/dev/sda2       /var/lib/mysql          ext3    defaults        1 2
/dev/sda5       /var/log/httpd         ext3    defaults        1 2
/dev/sda6       /var/www                ext3    defaults        1 2
/dev/sda3               swap                    swap    defaults       
0 0

Since I was not successful on the install, I did not add/change the
/dev/sda# to /dev/i2o/hda#.  (Device names do change from /dev/sdL# in
RH to /dev/i2o/hdL# in FC3+.)

In my pay job I am don't have the ability to use LABEL on a partition. 
Are you thinking I may be able to change the /dev/sda# to LABEL and
install that way?  Since the Fresh and the Upgrade install "found" the
drive successfully, I wouldn't think that Anaconda reads the fstab. 
(I'm not familiar with Anaconda, so my logic could be wrong.)
