  There's always going to be an argument about whether to put /boot and swap 
on RAID.  It's all about performance most of the time being slightly better 
versus stability in the event of device failure.

  What's the disaster recovery plan here?

  Obviously, if the second drive fails, there's no issue.  Standard removal 
and eventual addition of replacement device(s).

  If the first drive fails, are we hoping the computer will boot off the 
second drive or are we moving the second drive to the first interface?

  Is it outside the scope of this document to describe and test disaster 
recovery?  I think it is.  I'm just making a note to suggest a further 
complimentary page at some time in the future...  (though, at this time, I 
am NOT volunteering to write it)  Is there a wiki page todo list somewhere?
