Raid for swap?  I see how it is technically feasible but is there really
a reason to do this?  If this is s/w raid and you can't hotswap, isn't
the swap contents useless after a reboot?

I realize I'm not addressing your question.  I have never used s/w raid,
so I'm truly curious about raiding swap.

Is the swap partition just redundancy?  In this case reading a page back
into the kernel could be serviced from either drive, is the the reason
to raid swap?
