I didn't completely follow that.  can you explain what the tar cp 
statement is doing?  Also, I think I need to be more specific when I 
said there was space left at the end of the LVM drive (hdb).  The drive 
is one big LVM partition, covering the entire drive.  The space 
remaining that I mentioned is space inside the LVM physical volume that 
is not allocated to any logical volumes.  Can LILO handle this, when 
/boot is LVM'd and RAIDed?
