This brings up something I'm wondering.  I'm experimenting with SuSe 
Standard server, and installed it on a Dell server, with 4 SCSI drives. 
 I have configured part of the system with RAID, but it won't allow 
/boot to be on a RAID drive.  Since with hot swapping, you want all the 
drives to have the same layout, what happens, if the drive with /boot on 
it fails?  How do you recover from that?  I had considered copying the 
/boot partition to the other 3 drives, but I'm not sure what would be 
the next step to recovering the system.
