Custom boot disk (ATA100 support) + RH7 CD.  The system is running RAID1 
on all partitions.  If I select the upgrade path, I get the following 
exception.  I cannot seem to get it to save to floppy (i put in a new 
floppy and the disk moves and then I'm asked for another one, rinse and 
repeat) so I'm typing it in.  Hopefully I'll have gotten everything.  

The RAID is autostarted (all are fd and the status of the raid starting 
goes by at boot).  Note: that I must manually create each raid device 
in /dev, and do a raidstop on each too boot cleanly.  Simply ctrl-alt-del 
causes an oops.

SystemError: (17, 'File exists')

======

/tmp/member does exist -- looks like a big binary file.

Resolution: stop all raid devices *before* starting the upgrade thing.  If 
I go to the bash prompt (VC2), do a:

cd /dev; for i in 1 2 3 4 5 6 7 8 9 10; do mknod md$i; done
for i in md*; do raidstop /dev/$i; done

Then let the upgrade continue.

Reproducible: Always
Steps to Reproduce:
1. Do an upgrade install
2.
3.
