There are a couple of reasons, although they may make no sense. First,
I did not want a multiple point of failure. If the boot loader is on
the MBR of /dev/sda, and the os is on /dev/sdb, then you have a multiple
point of failure. If either card dies, then I am hosed. It would be
*similar* to running a RAID0 on the os. Not a good idea IMHO.
Also, if I wanted to replace the "data" drives in the future, I couldn't
just unmount the partition and replace the drives. The boot loader
would be gone as well.
I did not find an option during the install prep to re-locate grub to
the MBR of /dev/sdb. I probably should try the text-based installer to
see if there are more options.
Heck, I may just remove the 9550 board until the initial os install is
completed. That should accomplish what I am trying to achieve. Just
seems like there should be a more elegant way of doing this.
I am installing 5.1 because I have the isos on hand. I was just going
to let yum update me to 5.2...
Thanks for your help,
