I was doing an install on a test server and during the disk space check 
the RH install program noted that I did not have enough space allocated in 
one of my partitions.  I went back to Disk Druid and deleted all non-swap 
partitions and put in just one large root partition.  The installer threw 
an exception several screens later and generated the error report included 
below which it saved to a floppy.  I restarted the installation and 
everything proceeded without error after that.
