Well... it will actually round things down a bit to fit the smallest 
of the components.  So if need be, you could use a smaller partition 
on a bigger disk or something, in the event that you can't get
an exact replacment.

This step is *not* necessary if the "RAIDframe autoconfig stuff" is 
used.  And the "RAIDframe autoconfig stuff" *should* be used.  
Failure to use it means just asking for trouble if something gets 
mixed up.  (If you're using the autoconfig stuff, you can shuffle 
disks from one SCSI controller to another, or move IDE disks from one 
channel to another.  RAIDframe won't care, and will glue together the 
appropriate components in the correct order.)

This is old... yes, I know it's still in 1.6.x, but the reality is 
that it doesn't apply any more (raid.4 in 1.6.x is just out-of-date).
This stuff has already been removed from the man-page for -current.

I havn't had a chance to look over the rest of the document, but from 
the little I have seen it looks great, and I certainly do thank you for 
writing it! :)

Later...
