Aha! The truth comes out! I've only done SW RAID1. I try to avoid  
RAID5 as much as possible, although you bring up a good point that I  
want to make sure I understand. Are you suggesting not to run SW RAID5  
on /? Or are you suggesting to avoid using the same CPU that runs the  
system to also perform the RAID5 calculations?

If it's the OS, my ultimate goal is a SW RAID1 of CF cards :) But I  
think I'll settle for a single CF card and will just back it up  
elsewhere. It might not be a bad idea to RAID these guys. I see all  
sorts of negative reviews on NewEgg about someone getting burned by  
this. I suppose I could put LVM on top of the CF card, snapshot that,  
and then dump the FS onto another CF card. But now we're getting into  
really weird territory :) That and I don't believe in running LVM on  
the root file-system. In fact, I don't like running EXT3 on root  
either. I'd live with XFS, but I usually keep /boot to EXT2.

I suppose I could simply backup the CF card onto the storage drive  
(with the LVM + RAID goodness). Only problem is that, on a restore, I  
would need to login to a rescue environment and configure software  
RAID manually, then LVM (which should be stored in header information  
anyway) just to get the system image back.

That said, I could just backup to the Jungle :)

Anyways I went off on a tangent so I'll just stop here :)
